TDAT042G5 Device Advisory
for Version 1 and 1A of the Device
System Programming (SP)
SP1. Required Provisioning Sequence and Clocks
The core registers must be written prior to provisioning any other registers (1) to establish the internal clock
rates for the device, and (2) because writing to certain core registers resets the remainder of the device. Cer-
tain clocks must be present to read/write registers prior to provisioning the device.
One of the following clocks must be present prior to provisioning to enable register access:
I
TxCKP and TxCKN
I
MPU clock (microprocessor interface synchronous mode only)
Provisioning must be implemented in the following sequence:
I
Core register 0x0010 (mode) must be provisioned first
I
Core register 0x0011 (channel [A--D] control) second
I
Remainder of the core registers must then be provisioned (order does not matter)
It is recommended, but not required, that the remainder of the device be provisioned in the following order:
I
OHP, PT, and DE blocks (order does not matter)
I
UT block to turn on the data source to the master and slave
Workaround
Provisioning must be implemented in the following sequence:
I
Apply either TxCKP and TxCKN or MPU clock.
I
Provision core:
-- Mode, register 0x0010
-- Channel [A--D] control, register 0x0011
-- Remainder of the core
Corrective Action
Not applicable. Use above procedure in provisioning the device.

SP2. Behavior During Loss of Receive Line Clock
All state and counter values will be held at their current values when Rx line clock has been lost. The device will not
automatically multiplex in the Tx line clock when the Rx line clock is lost.
Workaround
System software should monitor loss of line clock bits in the receive/transmit state register (addresses 0x040A--
0x040D) and ignore all other alarms. This condition must be serviced as a major failure event.
Corrective Action
This is informational only. No corrective action is required for this condition.
SP3. PT Register Addressing
Addresses for the PT error counter registers are as follows:
I
Channel A: 0x09B3 to 0x09E3
I
Channel B: 0x09EF to 0x0A20
I
Channel C: 0x0A2C to 0x0A5C
I
Channel D: 0x0A68 to 0x0A98
Note: The reserved address space between the error counter registers is not symmetric. (The reserved space
between channels B and C is 0x003D, and the reserved space between channels A and B and channels
C and D is 0x003C.)
Workaround
This is informational only. No workaround is available for this condition.
Corrective Action
No corrective action is required for this condition.

Microprocessor Interface (MPU)
MPU1. Interface to Motorola* MC68360 Processor Is Not Glueless
The interface between the Motorola MC68360 processor and TDAT042G5 requires intervening logic because of
the following incompatibilities in the specifications of these two devices. For a 33 MHz microprocessor clock rate,
the Motorola MC68360 series processors can be interfaced to TDAT042G5 without intervening glue logic, if used
without DT and if programmed for six wait-states. If a user wishes not to use the wait-states, then the chip select
applied to TDAT042G5 must be held low until the address changes. Details are given below.
Chip Select Timing
The TDAT042G5 CS input signal requirements are not compatible with the Motorola MC68360 series processor
CSx output signals. TDAT042G5 timing does not allow simultaneous deassertion of CS and ADS signals. Chip
select applied to TDAT042G5 must be held low for at least 5 ns after the MC68360 deasserts ADS.
Workaround: Use external glue logic to decode the address to generate CS, or provide microprocessor interface
signals meeting the requirements of TDAT042G5.
DT Timing
If the Motorola MC68360 processor CSx signal is used to drive the TDAT042G5 CS, then TDAT042G5 DT output
does not satisfy the MC68360 processor DSACK timing requirement. DT is not pulled to 1 before it is placed in a
high-impedance state. This causes the next MPU cycle to be terminated early.
Workaround: Place a 1 k
resistor from DT to V
DDD
.
Corrective Action
Corrective action for MPU1 has not been determined.
MPU2. Synchronous Microprocessor Interface Mode Is Nonfunctional
The synchronous microprocessor interface mode, MPMODE = 1 (pin D8), functions as described in the advance
data sheet, but causes data errors. Placing TDAT042G5 in the synchronous mode and placing a clock on MPCLK
(pin C8) will cause the data passing through the device to be corrupted. Data errors are generated at a rate of 1%
or less of corrupted packets.
Workaround
Use the TDAT042G5 in the asynchronous microprocessor mode, MPMODE = 0, with no clock applied to MPCLK.
Corrective Action
This condition will be resolved in version 1A of the device.

This is informational only. No workaround is available for this condition.
Corrective Action
This condition will be described in revision 4 of the advance data sheet.
Line Interface (LI)
LI1. STS-48/STM-16 Mode Lacks Facility Loopback
There is no facility loopback function (line input to line output) available in STS-48/STM-16 mode. Facility loopback
is available only in STS-12/STM-4 and STS-3/STM-1 modes as described in the advance data sheet.
Workaround
This function is not a feature of TDAT042G5.

PT1. Signal Degrade (SD) and Signal Fail (SF) Bit Behavior
Receive signal degrade and receive signal fail bits in the PT state registers (addresses 0x0838, 0x088A, 0x08DC,
and 0x092E, bits [1:0]) do not function as described. Until the signal degrade (SD) and signal fail (SF) thresholds
are programmed, the SD and SF bits will toggle on a frame-by-frame basis.
Workaround
Program thresholds during system software initialization.
Corrective Action
This functionality will be retained in its current state in future versions of the device. The advance data sheet will be
corrected to reflect the actual function of the registers.
PT2. Clear-After-Write Behavior of Signal Degrade Clear Bits
Signal degrade clear (bits 15--12) of the PT one-shot control parameters register (address 0x0AA4) are described
as one-shot, clear-after-write bits. Writing these bits should automatically set and then clear the bits. This one-shot
behavior is not observed.
Workaround
The bits must be set to 1 and then explicitly set to 0 to clear these signal degrade bits.
Corrective Action
This functionality will be retained in its current state in future versions of the device. The advance data sheet will be
corrected to reflect the actual function of the registers.

PT3. Remote Defect Indicator (RDI) Behavior
The SONET standards require that when an RDI changes value, it should hold the value for a minimum of
20 frames. This applies to a no error state, which should be maintained for at least 20 consecutive frames.
However, it is also intended by the SONET standard that the occurrence of an error state should be reported
immediately.
TDAT042G5 responds to error conditions within 100 ms (ANSI
*
T1.105 which states only that RDI-L must be gen-
erated or removed within 100 ms of detecting or terminating an incoming defect), in which case the two require-
ments become functionally the same.
Single-bit and enhanced RDI behave differently under the following conditions:
I
Transition from error state to no error state.
I
While in the error state, a subsequent error occurs.
The single-bit error RDI does not hold the no error state for 20 frames. However, the enhanced RDI does hold the
no error state for 20 consecutive frames.
Workaround
No workaround is available for this condition.
Corrective Action
The enhanced RDI indicator in future versions of the device will behave the same as the single-bit error indicator.
PT4. SS Pointer Interpretation Algorithm
The SDH standards do not require that the SS bits are set to binary 10 for SDH equipment. The SS bit values are
not used in determining a valid pointer value. Because of this, the SS pointer interpretation algorithm is not imple-
mented in the device. Bit 5 (RSSPTRNORM[A--D]) of PT control registers 0x0AA6, 0xAAE, 0x0AB6, and 0x0ABE
is not used. Bits 1 and 0 (RSSEXP[1:0]) of PT provisioning register 0x0AC7 are not used.
Workaround
No workaround is available for this condition.
Corrective Action
These bits will be removed from the PT registers in future revisions of the advance data sheet.

Because there is a one-cycle delay before the PT delta event registers (0x802, 0x080F, 0x081C, 0x0829) are
cleared after being read in COR mode, new interrupts may be lost.
Workaround

This condition will be addressed in future versions of the device.
DE2. Incorrect ATM Loss of Cell Delineation (LCD) Implementation
Currently, the LCD is implemented in the same way that out of cell delineation (OCD) is implemented. This is not in
accordance with the ITU-TI.432-2 February 1999 standard.
Workaround
No workaround is available for this condition.
Corrective Action
A software workaround will be available with version 1A of the device.

DE5. Packet Behavior in POS/SDL Mode--Dry Mode
When the device is configured in POS mode with dry mode enabled, the following conditions may persist:
I
PPP mode; STS-48/STS-12/STS-3.
When running in PPP mode, the PPP header--0xFF03 0x0021 (provisionable)--may be incorrectly inserted at
any point in a packet within the outgoing data stream when the FIFO runs dry, thereby corrupting the packet.
Packets being sent are corrupted if the FIFO runs dry.
I
PPP and CRC modes; STS-48/STS-12/STS-3.
CRC, PPP, and HDLC modes; STS-48/STS-12/STS-3.
In PPP, CRC, and HDLC dry modes, some of the packet data may be corrupted when the packet length is above
a certain size where size is dependent upon UT clock rate and low watermark setting. Either sections of the
packet may be lost or additional packets may be inserted.
Workaround
Several workarounds are possible:
I
Do not provision dry mode for this device.
I
If dry mode is provisioned:
-- Do not allow the FIFO to be emptied.
-- Run the UTOPIA clock fast enough, as shown in Table 3, so that the FIFO is never empty.
-- Use a larger external FIFO to buffer the data.
-- Do not allow the packet size to exceed the low watermark.

DE6. Incorrect ATM Out of Cell Delineation (OCD) Implementation
In ATM mode, the OCD reporting for channels B, C, and D is incorrect. The OCD state of channel A is reported for
channels B, C, and D. The OCD reporting is correct for channel A.
Workaround
No workaround is available for this condition.
Corrective Action
This condition will be corrected in version 1A of the device.
DE7. Incorrect Frame State of ATM Data Streams
When sending a single ATM data stream to channel A, the frame states of channels B, C, and D are incorrectly set
to sync mode. This prevents LCD errors from being reported on channel A as well. In addition, when sending a sin-
gle ATM data stream to channels B, C, or D, the frame states always remain in hunt mode. This results in LCD
errors on those channels.
Workaround
No workaround is available for this condition.

DE8. Clearing DE Interrupt Register (0x1002)
DE interrupt register 0x1002 is incorrectly defined in the revision 3 of the data sheet as RO. DE interrupt register
0x1002 is correctly defined as a COR/W register. However, register 0x1002 must be used in the COR mode (regis-
ter 0x0010 bit 6 set to 1). The bits of register 0x1002 are explained in detail in Table 4.
Table 4. Register 0x1002: DE Interrupt (COR/W)
Workaround
This is informational only. No workaround is available for this condition.
Corrective Action
This behavior will be described in future revisions of the advance data sheet.
DE9. Single Packet Transmission in HDLC-CRC, SDL-CRC, and PPP Modes
When receiving in either PPP or CRC mode, a single packet may not pass through the device. This occurs when
the end of packet (which contains the CRC) never reaches the UT FIFO. The ingress channel suspends transfer to
the UT when there is no end of packet in the FIFO. These bytes are transferred to the UT when the next packet is
received. This problem will affect HDLC-CRC, SDL-CRC, and PPP modes.
Workaround
There are two possible workarounds:
I
Set ingress payload type and mode control registers (0x1040--0x1043) to CRC strip mode. However, in CRC-16
mode, single packets may still get stuck if CRC ends on bytes A or B.
I
Send a minimum 4-byte dummy packet after each packet.

DE10. Excessive HDLC Flag Characters
The following three issues refer to HDLC flag character (0x7E) problems in the data engine:
I
An excessive number of HDLC flag characters (0x7Es) may be inserted between packets on the transmit side if
the UTOPIA low watermark value is set above 2. This will have the effect of reducing the bandwidth of the device.
I
The data engine operates on 32-bit boundaries. Egress packets that are not multiples of four will be filled with
0x7Es.
I
Egress packets consisting of all 0x7Es as data will be corrupted.
Workaround
Set the UTOPIA egress low watermark value in the UTOPIA egress provisioning registers (0x0212, 0x0216,
0x021A, 0x021E) to either 1 or 2 to prevent excessive 0x7Es from being inserted between packets.
Corrective Action
This condition will be addressed in future versions of the device.
UTOPIA (UT)
UT1. Polling in Multidevice MPHY Mode
When the TDAT042G5 is polled and responds, the data bus becomes enabled. In a multidevice MPHY configura-
tion, if the data bus is active from a different PHY device, response to a poll from the device will corrupt a data
transfer already in progress. TDAT042G5 MPHY always functions without data corruption in a single-device
(slave), multiple-channel configuration (point-to-point).
Workaround
No workaround is available for this condition.

UT2. UTOPIA Clock Limitations
The maximum speed of the UTOPIA interface is 104 MHz. When operating at clock speeds greater than 52 MHz,
RxCLK[D:A] must be placed in source mode and will use the same external clock as the corresponding
TxCLK[D:A] clock. RxCLK[D:A] source mode is set by provisioning bit 6 (CLOCK_MODE_Rx) for channel A of the
UTOPIA receive provisioning registers (address 0x020F).
When operating at speeds less than 52 MHz, separate external clocks for RxCLK[D:A] and TxCLK[D:A] may be
used.
Workaround
This is informational only. No workaround is available for this condition.
Corrective Action
This condition will be addressed in future versions of the device. Design modifications will be directed towards
allowing a maximum interface speed of 104 MHz in all cases. Note that UTOPIA Level 3 clock architecture has
changed in the ATM Forum's UTOPIA Level 3 specification as of the July 1998 version.
UT3. PMRST Register Value Invalid After Reset
The value in PMRST_PECTx[A--D] (addresses 0x020B through 0x020E) is invalid after reset until the second
PMRST clock period is completed. After the second PMRST, the register value is valid.
Workaround
Always have the system software execute a read of PMRST_PECTx as part of the system initialization following a
reset.
Corrective Action
This condition will be addressed in future versions of the device.

UTOPIA (UT)
(continued)
UT4. FIFO Overflow and Error Reporting
If the RxFIFO overflows, RxEOP is not asserted as expected. Therefore, when errors occur, two packets will be
corrupted instead of one because two start of packets (SOPs) occurred without an end of packet (EOP). RxERR is
not asserted when the above overflow condition occurs. No effect is noticeable in the ATM mode. Channel A works
as expected; this problem occurs in channels B, C, and D.
Workaround
This error is detectable in the status registers. No workaround is available for this condition.
Corrective Action
This condition will be addressed in future versions of the device.
UT5. Timing Difference Between Direct and Polled Status Modes
In the receive direction of the MPHY mode, RxPA[A] shows the polled packet (or ATM) available status for all four
slices, while the RxPA[B], RxPA[C], and RxPA[D] show the direct status states of their respective FIFOs. In some
cases, the status of RxPA[A] does not agree with the status of RxPA[D:B]. The direct status indication has one
additional cycle of pipeline delay from that of the polled status.
Workaround
This is informational only. No workaround is available for this condition.
Corrective Action
No corrective action is required for this condition.
UT6. UTOPIA Interface D Nonfunctional in Some Mixed MPHY and Point-to-Point
Configurations
When TDAT042G5 is configured with slice D in a point-to-point mode, slice D is nonfunctional in one special case.
If UTOPIA interfaces A and B are configured for 32-bit MPHY operation with slice C as part of the polled channels,
interface D will be nonfunctional and cannot be independently configured in a UTOPIA Level 2 point-to-point mode.
This condition does not occur in 16-bit MPHY operation.
Workaround
For mixed MPHY and point-to-point configuration, use UTOPIA slice D for MPHY mode instead of slice C.
UTOPIA slice C will then be available for normal point-to point mode.
Corrective Action
This condition will be addressed in future versions of the device.

TDAT042G5 MPHY currently generates a polled status response to the address 0x1F (the null address), which is
not compliant with the UTOPIA Level 2 standard. The address 0x1F is valid for UTOPIA Level 3 operation.
Workaround
No workaround is available for this condition.
Corrective Action
This condition will be addressed in future versions of the device.
UT8. Far-End Loopback Bandwidth Limitations
In the STS-48/STM-16 mode (U3, U3+), looping back data at the far end (UTOPIA interface) can only be accom-
plished without cell/packet corruption at rates below the following, as shown in Table 5.
Table 5. Cell/Packet Corruption Rates
When cell/packet corruption occurs, the device reports transmit FIFO underflow.

UT9. Clock Requirements for MPHY Modes
When using the TDAT042G5 in MPHY mode, receive and transmit clocks must be provided for all channels (A, B,
C, and D). Also, the packet available (PA) signal for each channel must be provided on each channel's associated
PA pin.
Workaround
It is possible to place RxCLK[D:A] into source mode by provisioning bit 6 (CLOCK_MODE_Rx) of the UTOPIA
receive provisioning registers (addresses 0x020F, 0x0213, 0x0217, 0x021B). This will eliminate the need to supply
separate receive and transmit clocks.
Corrective Action
This is informational only. No corrective action is required for this condition.
UT10. Egress Packet Mode Overflows
In the UTOPIA modes listed below, the device will report transmit packet overflow errors when no overflows have
occurred. This occurs when the egress high watermark is set for the UTOPIA modes as shown in Table 6.
Table 6. Settings at Which Overflows Reported in Error
Workaround
Set the egress high watermark threshold as shown in Table 7. If there is a delay between TxPA deassertion and
TxENB deassertion, the additional cycles should also be accounted for when setting the threshold.

UT11. Clearing UT Interrupt Register
When a UT interrupt event occurs and COW mode is enabled, writing to UT interrupt register 0x0201 does not
clear the register (this register is read-only). The interrupt is cleared by writing to the UT delta and event registers
(addresses 0x0202--0x0205).
Workaround
This is informational only. No workaround is available for this condition.
Corrective Action
No corrective action is required for this condition.
UT12. Incorrect Implementation of POS Multi-PHY Mode
Because the TDAT042G5 lacks a selected PA signal (SPA), the status of a channel that is transmitting data in POS
MPHY mode is not known during polling. Therefore, the PA signal cannot be used as a data valid signal. If the
channel transmitting data runs dry, the master side may receive invalid data.
Workaround
Use direct status polling mode only and ensure that the address of channel A is applied to the address bus at all
times, except during the clock cycle when another channel is being selected.
Corrective Action
No corrective action is required for this condition.
UT13. Invalid Extra Cycle Between EOP and SOP in CRC-16/32 Mode
When using the device in CRC-16 or CRC-32 mode, there is always an extra cycle between the end of packet
(EOP) of the previous packet and the start of packet (SOP) of the following packet.

UT14. Nonfunctional RxPA Signal for Channels B and D in Packet Direct Status MPHY Mode
When using MPHY direct status for all operational modes (8-bit, 16-bit, and 32-bit), the RxPA signal for channels B
and D is not functional. The RxPA signal is functional only for channels A and C.
Workaround
The TDAT UTOPIA interface currently has nonfunctioning RxPAB and RxPAD output signals when used in four-
channel Multi-PHY mode as shown in Figure 1. The result of this problem is the unavailability of direct status polling
on the receive-side UTOPIA interface. To work around this problem, the following analysis is done to aid the user in
doing a round-robin data extraction procedure.
1664 (F)
Figure 1. Receive-Side UTOPIA Interface and Channel FIFOs
The rate at which data fills and drains the receive-side UTOPIA FIFOs is calculated as follows:
I
The data enters each UTOPIA FIFO from the data engine bytewise running on a 77.76 MHz system clock.
I
If we assume each channel (worst case) is filled with an STS-12c rate signal, then the amount of data (excluding
SONET overhead, both section/line, path, and three stuff columns) per second is
(87 x12 x 9 x 8000) (4 x 9 x 8000) = 74.88 Mbytes/STS-12c/s or 599.040 Mbits/STS-12c/s.
I
Since each FIFO contains a maximum of 256 bytes/FIFO, it takes on average
(256/74,880,000) = 3.4188
s to fill a FIFO, and with a clock cycle of 77.76 MHz, it requires as a worst case,
3.2922
s to fill the FIFO.
I
Since there are four FIFOs all receiving data at 74.88 Mbytes/s, then the total bandwidth requirements of all four
channels combined is (4 x 74,880,000) = 299.52 Mbytes/s.
I
The servicing rate on each FIFO is based on the UTOPIA interface width and frequency. If we assume a
32-bit A/B UTOPIA interface operating at 100 MHz, then the service rate is 400 Mbytes/s to service all the
channels.

TDAT042G5 Device Advisory
UTOPIA (UT)
(continued)
I
The interface can drain an entire FIFO at a rate of 400 Mbytes/s. To drain 256 bytes, it requires a maximum of
(256 / 400,000,000) = 0.64
s to drain a FIFO that is completely full. To drain all four FIFOs, it requires
(0.64 x 4) = 2.56
s total
.
For data to be efficiently removed from each of the Rx FIFOs, a round-robin extraction method must be employed
since the RxPAB and RxPAD signals are not available for direct status polling. Since it requires a worst case total of
3.2922
s to fill a FIFO, the master must service all FIFOs in a manner such that it does not allow any particular
FIFO to fill and hence overflow. Assuming equal servicing of each FIFO, the master must therefore not service any
particular FIFO for longer than (3.2922 / 4) = 0.8231
s. This also must account for any dead cycles in a cycling
between channels and any dead cycles on a particular channel (single dead cycle between EOP and SOP).
When servicing four FIFOs, there is a maximum clock cycle penalty for switching between channels. For two-cycle
mode, this penalty is a maximum of four UTOPIA master clock cycles; so to switch between all four channels, a
total of up to sixteen master clock cycles may be required to perform all the switching. The value of four is worst
case, and in some cases this can be as low as one cycle. The value of four results from the case where the FIFO
drains while servicing that channel, which will be common when draining at the 100 MHz frequency. In that case,
the master must first see that the FIFO has drained by observing that RxPAA is invalid on the last cycle while drain-
ing the FIFO (best case is one cycle lost). It must then deactivate RxENB and place a new channel address on the
address bus on the following cycle (best case is one cycle lost). It must then activate RxENB for the new channel
on the following cycle and have TDAT sample RxENB low (best case is one cycle lost). The TDAT will then output
data two cycles later when using a PA response mode of two cycles (one cycle lost with data output on second
cycle). Any additional delays by the master must be added to these to calculate a worst-case condition. The best-
case condition occurs when the master stops the data flow when there are still more than two data items contained
within the FIFO. In this case, the master deactivates RxENB at some predetermined maximum 32-bit word drain
value, where the PA response on the cycle prior to deactivation had valid data. For two-cycle mode, two additional
data items will be output from the FIFO for that particular channel, if available. The master deactivates RxENB,
places the new channel address on the FIFO, and activates RxENB. On the cycle where RxENB is activated, the
last valid data item from the previous channel may be output (best case), and one dead cycle will follow this before
data for the following selected channel is output.
Given the information above, assume the worst case of four cycles between channel switching. Also assume the
FIFOs are filling at a worst-case rate, 3.2922
s/FIFO. Assume the master is draining each FIFO using the 32-bit,
100 MHz, A/B, UTOPIA interface. Assume the master extracts a maximum of thirty 32-bit words (120 bytes) from
each FIFO before switching to an alternate channel. This requires (30 x 10) = 300 ns/FIFO, and assume that it
takes the worst-case four clock cycles to switch to alternate channels. Therefore, the total servicing time per FIFO
is (300 + 4 x 10) = 340 ns/channel, and the total servicing time per four channels is (4 x 340) = 1.36
s per round
robin servicing of all four channels. At this round-robin rate, a maximum of 120 bytes are serviced per channel per
1.360
s interval; so to service the total bytes per channel (74.88 Mbytes/s), it requires a total of 0.849 seconds,
which is sufficient bandwidth to service all channels.
Since the FIFOs fill at the maximum rate of 1 byte/13.355 ns, each FIFO will fill to a depth of 102 bytes in the
1.360
s interval between channel servicing. This is well below the overflow threshold, which is set by the user to a
value near the top of the FIFO (high watermark, 0x36 (216 bytes) default) and is below the number of bytes ser-
viced by the master per channel per round-robin servicing (120 bytes). Each customer's servicing characteristics
will depend on the master's behavior and how fast it performs the channel switching. If it cannot switch in the worst-
case, four-cycle manner described above, performance will degrade.
One item not accounted for in the above analysis is the fact that TDAT may place a dead cycle between packets (in
CRC and PPP modes, not in HDLC mode). In this case, there can be a maximum of three dead cycles per FIFO
(assuming 40-byte packets worst case and 102 bytes in FIFO between round-robin cycle). This will be taken up by
the slack provided above, where (102 bytes + 4 bytes/dead cycle x 3 dead cycles) = 114 bytes, which still falls
below the servicing rate of 120 bytes per round-robin servicing.

OHP1. Maximum BER Count
The maximum number of errors the device can report is limited to 5.00E-04 in STS-12/STM-4 mode and 1.00E-04
in STS-48/STM-16 mode. This applies to the SDLSET, SDLCLEAR, SFLSET, and SFLCLEAR bits of the signal

Workaround
This is informational only. No workaround is available for this condition.
Corrective Action
No corrective action is required for this condition.
OHP2. RDI-L Reporting
When the device is initially powered up, it defaults to STS-48/STM-16 mode. This locks a counter value into trans-
mit control registers for channels B, C, and D. When the device is configured for STS-3/STM-1 mode, the counter
does not automatically clear.
Workaround
During STS-3/STM-1 OHP configuration in the system code, manually clear transmit control registers 0x0431,
0x0433, and 0x0435 for channels B, C, and D. In order to clear these transmit control registers, the bits must be
toggled. The following pseudocode shows how to clear the bits on channels B, C, and D:
Set address 0x0431 to 0x007F # set bits on channel B
Set address 0x0431 to 0x0000 # clear bits on channel B
Set address 0x0433 to 0x007F # set bits on channel C
Set address 0x0433 to 0x0000 # clear bits on channel C

OHP3. M1 Error Counter in STS-48/STM-16 Mode
When the device receives REI-L errors in the STS-48/STM-16 mode, no M1 errors are reported.
Workaround
There are several workarounds for this problem:
I
Pass the B2 error count value to the far end through system software.
I
Process the M1 byte from the receive TOAC with an external FPGA.
I
Pass the B2 error count from the receive to the transmit direction using transmit TOAC capability. The error count
must be inserted into the eleventh Z2 byte in an STS-48/STM-16 transmit signal. The transmit TOAC signal is
driven by an external device with software insert capability.
I
Pass the B2 error count from the receive to the transmit direction in the section overhead byte. The device has F1
and S1 monitor capability; the protocol for sending the error message to the far end with F1 or S1 bytes is user-
defined.
Corrective Action
This condition will be addressed in future versions of the device.

155/622/2488 Mbits/s Data Interface
TDAT042G5 SONET/SDH
Description
The TDAT042G5 SONET/SDH interface device provides a versatile solution for quad STS-3/STM-1,
quad STS-12/STM-4, and for single STS-48/STM-16 point-to-point datacom/telecom applications. Constructed
using Agere Systems Inc.'s state-of-the-art CMOS technology, this device incorporates integrated SONET/SDH
framing, section and line overhead insertion and extraction, path termination, and generation.
The integrated circuit provides complete encapsulation and decapsulation for packet and ATM streams into and
out of SONET/SDH payloads.
Communication with the device is accomplished through a generic microprocessor interface. The device supports
separate address and data buses.
With the device, construction of all types of point-to-point STS-3/STS-12/STS-48 (STM-1/STM-4/
STM-16) data equipment is simplified and cost-reduced, allowing extremely efficient solutions.
Pin Information
TDAT042G5 is available in a 600-pin LBGA package. The pin diagram is shown in Figure 1. For convenience, pin
assignments are listed by pin order in Table 1 and by signal name in Table 2. The pin descriptions as well as the
pin assignments are listed in Table 3--Table 10 and are grouped by interface type.

Pin Information
(continued)
Note: 3.3 V CMOS logic inputs are 5 V tolerant. Logic inputs can be driven from standard TTL levels, and logic out-
puts can drive standard TTL inputs. All LVPECL buffers are differential. LVPECL is compliant with low-volt-
age (3.3 V) pseudo-emitter-coupled logic interface levels. All PECL outputs, including ECLREFHI and
ECLREFLO require terminating resistors. The required termination for the PECL buffers is 50
to a termi-
nating voltage of V
DDD
2 V. The Thevenin equivalent is also acceptable (130
to V
DDD
and 82
to
GND
D
). Other termination styles are not recommended. LVPECL inputs with a / in the name indicate multiple
functionality. The name preceding the / is the function in STS-48/STM-16 mode. The name after the / is the
function in STS-3/STM-1 or STS-12/STM-4 mode.
Table 3. Pin Descriptions--Line Interface Signals
Unused LVPECL outputs should not be terminated to minimize power consumption. Unused inputs are internally
disabled whenever core registers 0x0010 and 0x0011 are properly provisioned. The unused inputs can be consid-
ered to be NC (no connect).

All 32 differential data input pins, RxD[15:0]P/N, are used as the parallel
data input bus in the STS-48/STM-16 mode. These pins constitute a
155.52 Mbits/s parallel 16-bit word-aligned to the RxCKP/N 155.52 MHz
receive line clock. RxD[15] is the most significant bit and is the first bit
received. RxD[0] is the least significant bit and is the last bit received.

Note: The TDAT042G5 has internal circuitry that is associated with the buffer section of the chip. This section
monitors the voltage levels of REFLO and REFHI. A very low frequency calibration process, during which
the values at the ECLREFLO and ECLREFHI pins are continuously monitored, is performed to allow the
drive capactity of remaining buffers to be adjusted within true PECL levels. Therefore, it is important to ter-
minate the ECLREFLO and ECLREFHI outputs in exactly the same way as you would terminate LVPECL
outputs.

TxCKP/N is used to clock out the data. In the contra-clocking
mode, the transmit line clock PLL must be active (see core regis-
ter map 0x0010, bit 5 (PLL_ MODE) on page 112).
This clock is not used in the STS-3/STM-1 or STS-12/STM-4
modes.

Transmit Line Data Outputs (STS-48/STM-16). In STS-48/
STM-16 mode, these pins function as transmit line data outputs
[4:15]. The remaining transmit line data outputs [0:3] are listed
below and are multiplexed for use in the STS-3/STM-1 or STS-12/
STM-4 modes.
The 155.52 Mbits/s 16-bit word parallel bus is converted to a
2.488 Gbits/s serial data stream external to TDAT042G5 by a mul-
tiplexer.
All 32 differential data output pins, TxD[15:0]P/N, are used as the
parallel data output bus in the STS-48/STM-16 mode. These pins
constitute a 155.52 Mbyte/s parallel 16-bit word-aligned to the
TxCKP/N and TxCKQP/N 155.52 MHz transmit line clock.
TxD[15] is the most significant bit and is the first bit transmitted.
TxD[0] is the least significant bit and is the last bit transmitted.
This buffer is internally disabled through proper provisioning when
the input is not active.

O
Receive Line Frame. This output provides the receive 8 kHz
frame reference for external timing needs. RxREF is derived from
one of the received line clocks (user-selectable). It is a 50% duty
cycle clock when TDAT042G5 is in frame. This signal may be
used to implement line timing on a SONET ring. When not provi-
sioned, this signal must not be used. RxREF is valid only when
the SONET framer is in frame. Upon LOC or LOF, RxREF is
present but is free running. Because jitter may be present on this
signal when the device goes into and out of an LOC or LOF state,
it should not be used as a reference for TxFSYNCP/N.

device. If the FIFO is empty or more than the provisioned space is
available in the FIFO, TxPA[D:A] is set active.

Two-Cycle Delay Mode. This mode follows the UTOPIA Level
3 baselined text*. The TxPA response occurs two cycles after
the address is polled.

TxPA[D:A] Assertion. The TxPA[D:A] signal behavior relies on
the UTOPIA provisionable watermarks. In packet mode,
TxPA[D:A] goes high when the amount of data in the FIFO is
less than the high watermark setting. In ATM mode, TxPA[D:A]
goes high when the FIFO has space to receive a complete ATM
cell from the master. (This requires the high threshold to be set
appropriately by the user, i.e., set so that an entire cell can be
received once TxPA[D:A] goes active.)

TxPA[D:A] Deassertion. In packet mode, TxPA[D:A] goes low
when the amount of data in the FIFO reaches or exceeds the
high watermark. In ATM mode, TxPA[D:A] goes low when there
is not enough space in the FIFO to receive an entire ATM cell.
(This requires the threshold values to be provisioned properly,
i.e., set low enough such that when the high watermark is
reached, the transmission of the current cell can be completed
without overflowing the FIFO). In ATM mode, TxPA[D:A] will be
deasserted four cycles before the end of the current cell trans-
fer if the FIFO cannot accept a complete ATM cell on the follow-
ing transmission.

In U3+ (8-bit mode), TxSZ[D:A] are unused.
For U2+ 16-bit mode,
TxSZ[D:A] = 0 defines the MSByte of TxDATA[D:A][15:0], i.e.,
TxDATA[D:A][15:8], to be the last byte of the packet transmit-
ted when using the default configuration.
TxSZ[D:A] = 1 defines the LSByte of TxDATA[D:A][15:0], i.e.
TxDATA[D:A][7:0], to be the last byte of the packet transmit-
ted when using the default configuration.
For U3+ (32-bit mode), TxSZ[A] and TxSZ[B] are combined to
define four states of the transmitted data stream. TxSZ[C] and
TxSZ[D] are unused. The following states are assigned by

Receive Cell/Packet Available. This signal indicates when the
TDAT042G5 receive FIFO can send data to the master device.
The RxPA[D:A] signal behavior depends on the provisioned low
watermark in the UTOPIA interface.
I
One-Cycle Delay Mode. This mode follows the UTOPIA Level
2 Standard. The RxPA response occurs one cycle after the
address is polled. RxENB is asserted to activate the selected
PHY. RxDATA and RxSOP are output one cycle after RxENB is
sampled active by the PHY device.
I
Two-Cycle Delay Mode. This mode follows the UTOPIA Level
3 baselined text*. The RxPA response occurs two cycles after
the address is polled. RxENB is asserted to activate the
selected PHY. RxDATA and RxSOP are output two cycles after
RxENB is sampled active by the PHY device.
I
RxPA[D:A] Assertion. RxPA[D:A] goes high (is asserted)
when the amount of data in the receive FIFO has reached or
exceeded the low watermark or there is end of packet (EOP)
resident in the FIFO.
I
RxPA[D:A] Deassertion. In ATM mode, the RxPA[D:A] signal
goes low (is deasserted) when the FIFO has less than the low
threshold amount of data and there is no EOP inside the FIFO
(i.e., part of an ATM cell). Once the last byte of the current cell
is transmitted, and if the amount of data within the FIFO is still
less than the low threshold, RxPA[D:A] is deasserted.
In packet mode, the RxPA[D:A] signal goes low (is deasserted)
when the FIFO has less than the low threshold amount of data
and there is no EOP inside the FIFO.
Once the data transfer begins (since the amount of data has
reached or exceeded the low watermark), and if there is no
EOP below the low threshold (i.e., a long packet), the RxPA
signal is deasserted when the FIFO is drained by the UTOPIA
master device. In this case, the master must closely monitor the
RxPA[D:A] signals and use these signals as data valid indica-
tors to ensure that bad data is not read from the TDAT042G5.
TDAT042G5 will deassert the RxPA[D:A] signal immediately
when the FIFO is drained.

Data Transfer. A TDAT042G5 ingress channel sends data
when it has asserted RxPA[D:A] and the master device
requests data (via RxENB[D:A]). In ATM mode, if the master
device requests data using RxENB[D:A] and if the TDAT042G5
has less than the low watermark amount of data to send and
there is no end of cell in the FIFO (RxPA[D:A] is deasserted),
then the TDAT042G5 UTOPIA interface will send out data that
should be ignored by the master, i.e., it does not send data from
its internal FIFO.
In ATM mode, once an ATM cell transfer starts, the Tx or Rx
side must complete the transfer. If the transfer is not com-
pleted, then the cell will be corrupted. The transfer continues
until either (1) the end of cell is reached, when the end of cell
exists below the low watermark, or (2) the end of the FIFO is
reached. If the end of the FIFO is reached, no underflow is
flagged on the receive side. In ATM mode, the low watermark
should be set so that at least one entire cell is in the FIFO prior
to asserting RxPA[D:A].
In packet mode, once the data transfer begins, the RxPA[D:A]
signal will remain asserted until the FIFO is drained if there is
no EOP below the low watermark. During the time RxPA[D:A] is
asserted, valid data is being transferred.
RxPA[D:A] is updated on the rising edge of RxCLK[D:A].
In 32-bit mode, only the RxPA[A] pin of port A is used to indi-
cate the packet/cell available status.
I
MPHY Support. When the RxPA signals are used for MPHY
direct status, the corresponding RxCLK[B, C, and/or D] must be
provided. This clock will be the same as RxCLK[A].

RxENB[D:A] is high, no operation is performed. If RxENB[D:A] is
low, the UTOPIA PHY Rx block sends data (not necessarily valid
data).
In U3 or U3+ (32-bit mode), only the RxENB[A] input pin of port A
is used to enable the transfer of data.

Receive Size. These pins are used only in U2+ and U3+ (packet)

packing within (1) RxDATA[D:A][15:0] for U2+ 16-bit mode, and (2)
RxDATA[A][15:0] and RxDATA[B][15:0] for the U3+ (32-bit mode).
The meaning of these bits may be inverted through UT register
0x0226 TxSIZE/RxSIZE mode, page 164.
In U3+ (8-bit mode), RxSZ[D:A] are unused.
For U2+ 16-bit mode,
RxSZ[D:A] = 0 defines the MSByte of RxDATA[D:A][15:0], i.e.,
RxDATA[D:A][15:8], to be the last byte of the packet received
when using the default configuration.
RxSZ[D:A] = 1 defines the LSByte of RxDATA[D:A][15:0], i.e.,
RxDATA[D:A][7:0], to be the last byte of the packet received
when using the default configuration.
In U3+ (32-bit mode), the MSByte will be placed on RxDATA[A],
bits 15 to 8. In the 16-bit mode, the MSByte will be placed on
RxDATA[D:A], bits 15 to 8.
For U3+ (32-bit mode), RxSZ[A] and RxSZ[B] are combined to
define four states of the received data stream. RxSZ[C] and
RxSZ[D] are unused. The following states are assigned by
RxSZ[A] and RxSZ[B] when RxEOP[A] is asserted and the

cates that the current packet is to be aborted and discarded, if
possible. RxERR[D:A] is only valid when RxEOP[D:A] and
RxENB[D:A] are asserted, and is updated on the rising edge of
RxCLK[D:A].
If the Rx FIFO overflows, RxERR[D:A] and RxEOP[D:A] are
asserted to indicate a corrupted packet.
RxERR is asserted when a CRC error occurs in any packet mode
using CRC-16 or CRC-32. RxERR is asserted when an incoming
packet has an abort flag at the end of its stream. In both of these
cases, an RxEOP is asserted with the RxERR.
RxERR is not asserted when a header does not match in PPP
header attaching mode. In that case, no data is sent to the UTO-
PIA interface.
In U3+ (32-bit mode), only the RxERR[A] output pin of port A is
used to indicate an error on the outgoing packet.

155/622/2488 Mbits/s Data Interface
TDAT042G5 SONET/SDH
Overview
This device integrates the SONET/SDH interface termination functions with a generic cell/packet delineation cir-
cuit. It supports STS-48/STM-16, quad STS-12/STM-4, and quad STS-3/STM-1 interface rates. Up to four data
channels transported within an STS-N payload are processed via the SONET/SDH termination blocks and the on-
chip data encapsulation/decapsulation engine. Packet or ATM data are transmitted/received by this device on the
equipment side via the enhanced UTOPIA interface. SONET/SDH streams are transmitted/received by this device
on the network side via the line interface.
Concatenation levels supported by this device range from STS-1 to STS-48c. Valid standard concatenated
SONET frame configurations for this device are STS-3c, STS6c, STS-9c, STS-12c, STS-15c, STS-18c, and STS-
48c. Non-standard concatenation levels (such as STS-4c, STS-5c, STS-7c, etc.) are supported as well. In STS-48
mode, four pointer processors are available. This allows an STS-48 frame to carry up to four concatenated sub-
frames (for example, mapping of four STS-12c payloads into an STS-48 frame). In quad STS-3 and STS-12
modes, only one pointer processor is available. Therefore, only a single subframe may be mapped into an STS-3
or STS-12 frame (mapping a single STS-3c payload into an STS-12 frame, for instance). For details, see Table 22
on page 68.
This device supports mapping for ATM cells into SONET/SDH, mapping for packet data via all existing or currently
proposed standards (e.g., PPP, SDL) into SONET/SDH streams. Via SDL mapping, this device also supports
packet over fiber or ATM over fiber, respectively. Figure 2 shows the overview block diagram, and Figure 3 shows
the interface block diagram for this device.

The receive path terminates and processes section, line, and path overhead. It performs framing (A1, A2),
descrambling, detects alarm conditions, and monitors section, line, and path BIP-Ns (B1, B2, B3), accumulating
error counts for each level for performance monitoring purposes. Line and path remote error indications (M1, G1)
are also accumulated. The payload pointers (H1, H2) are interpreted, and the synchronous payload envelope
(SPE) is extracted.
The transmit path inserts section, line, and path overhead. It inserts the framing pattern (A1, A2), performs scram-
bling, inserts AIS (optionally), and calculates and inserts section, line, and path BIP-8s (B1, B2, B3). Line and path
remote failure indications (M1, G1) are inserted based on received BIP-8 errors. The payload pointers (H1, H2) are
generated, and the SPE is inserted.
When used to implement an ATM UNI, ATM cells are written into an internal 4-cell FIFO buffer using a generic
8-/16-/32-bit wide UTOPIA 2/3 compliant interface. Idle/unassigned cells are automatically inserted when the inter-
nal FIFO is empty. The device provides generation of the header check sequence and optionally scrambles the
ATM payload.

TDAT042G5 SONET/SDH
Overview
(continued)
When used to implement a POS UNI, the device writes packets into an internal 256-byte FIFO buffer using a
generic 8-/16-/32-bit wide enhanced UTOPIA 2/3 compliant interface. HDLC framing performs the insertion of
flags, control escape characters, and the FCS fields. Either the CRC-ITU or CRC-32 (in regular or reversed mode)
can be computed and added to the frame. Counts of transmitted packets and errored/dropped packets are accu-
mulated for performance monitoring purposes.
ATM/HDLC/HDLC-CRC/PPP Support
TDAT042G5 supports the transfer of ATM cells or variable-length packets. Support for 52- or 53-byte cell sizes is
provided at the UTOPIA interface through register provisioning. The following three types of packet data can be
sent and received with HLDC-like framing: transparent HDLC, CRC, and PPP. Transparent HDLC contains 0x7E
framing but no CRC. CRC mode is HDLC with an attached CRC. PPP has 0x7E framing with provisionable
attached header information and CRC.
When used to implement an ATM UNI, the device performs cell delineation on the SPE. HEC error correction is
provided. Idle/unassigned cells may be dropped according to a programmable filter. Cells are also dropped upon
detection of an uncorrectable header check sequence error. The ATM cell payloads are descrambled before being
passed to a 4-cell FIFO buffer. The received cells are read from the FIFO using a generic 8-/16-/32-bit wide
UTOPIA 2/3 compliant interface. Counts of received ATM cells, uncorrectable HEC errors, and correctable HEC
errors are accumulated independently for performance monitoring purposes.
When used to implement a POS UNI, the device descrambles the SPE before extracting HDLC frames. The con-
trol escape characters are removed. Descrambling can be performed after control escape byte destuffing (or
before to control malicious HDLC expansion)
.
The optional 16- or 32-bit error check sequence is verified for cor-
rectness. The packets are placed into a 256-byte FIFO buffer.* The received packets are read from the FIFO using
a generic 8-/16-/32-bit wide enhanced UTOPIA 2/3 compliant interface. Counts of received packets and errored/
dropped packets are accumulated independently for performance monitoring purposes. The device POS imple-
mentation also allows the optional attach/detach of a per-channel provisionable PPP header.
* FIFOs are 256 bytes per channel and cannot be reallocated.

TDAT042G5 SONET/SDH
Overview
(continued)
Over-Fiber Mode
Over-fiber mode is used for packet delivery over fiber. No SONET overhead is added in this mode. Since no
SONET overhead is added, the OHP and PT blocks must be configured for the bypass mode.
In transmitting from the TDAT042G5 to the line, the data engine maps the data payload into a full SONET frame
starting at what normally would be the first A1 byte. The data engine continues to map payload into the full SONET
frame until an end of packet or end of frame is reached, at which time the data engine halts the mapping of the
incoming data stream into the SONET frame until the next start of frame.
When TDAT042G5 is receiving from the line, the data engine must be provisioned to receive the maximum packet
size, unless the location of the last byte of the packet is known in advance. If the size of the packet is not known,
one must program the data engine to receive the entire SONET frame. The external UTOPIA interface device must
then be capable of extracting the variable length packets from the full SONET frame.
Details of the over-fiber mode are given in the Data Engine (DE) Block section, page 82.
Test and General-Purpose I/O Support
The device is provisioned, controlled, and monitored using a generic 16-bit microprocessor interface. A standard
five-signal IEEE -1149.1 compliant JTAG test port is also provided for boundary-scan purposes.
A 4-bit GPIO (general-purpose input/output) interface is provided to control and/or monitor other onboard devices.

Functional Description
(continued)
Line Interface Block
This device is designed to work with commonly available optoelectronic converters for OC-3, OC-12, and OC-48
line rates. It will also work with available multiplexer and demultiplexer chip sets for an STS-48/STM-16 line inter-
face rate. The line interface will operate in one of three possible modes, and is provisioned through core register
0x0010 (mode), bits 4--0. These three values of the mode register are the only values allowed.
This block provides the interface between the external SONET/SDH line components and the overhead processor
(OHP) block. The line interface must provide transmit/receive functions for quad STS-3/STM-1, quad STS-12/
STM-4, and STS-48/STM-16 applications. All external inputs and outputs for the TDAT042G5 line I/O block are ref-
erenced to the positive edge of the clock. When the external devices are referenced to the negative edge, the dif-
ferential input clock will need to be reversed at the TDAT042G5 input.
Receive Line Interface Summary
The following list summarizes the receive line interface operations for each STS mode:
I
In quad STS-3/STM-1 mode, the receive line interface provides four separate STS-3/STM-1 input pin groups.
Each input group comprises a differential LVPECL 155.52 Mbits/s data input and a differential 155.52 MHz clock.
Each input group provides data to only one of four (A, B, C, or D) OHP blocks. This interface is synchronous and
requires an external CDR.
I
In quad STS-12/STM-4 mode, the receive line interface provides four separate STS-12/STM-4 input pin groups.
Each input group comprises a differential LVPECL 622.08 Mbits/s data input and a differential 622.08 MHz clock.
Each input group provides data to only one of four (A, B, C, or D) OHP blocks. This interface is synchronous and
requires an external CDR.
I
In the STS-48/STM-16 mode, the device provides 16 differential LVPECL data inputs at 155.52 Mbits/s with a dif-
ferential LVPECL 155.52 MHz clock. In this mode, an external 1:16 data demultiplexer with a 1/16 clock divider is
required. External barrel shifter circuitry to byte align the data is not required.
I
Multiplexers select between the terminal loopback data, the 32-bit parallel STS-48/STM-16 data bus, and the
four STS-12/STM-4 or STS-3/STM-1 8-bit parallel data buses. The controls for these MUXes are mode (register
0x0010) and loopback (register 0x0012) provided by the control block (see Table 48 and Table 50 on pages
150--151).
I
For STS-48 mode, the 155.52 MHz input clock is divided by two to 77.76 MHz and distributed to all four multi-
plexers. For the STS-12/STM-4 mode, each 622.08 MHz input clock is divided by eight to 77.76 MHz. Each
77.76 MHz clock is distributed to the appropriate clock multiplexer (A, B, C, or D). For the STS-3/STM-1 mode,
each 155.52 MHz input clock is divided by eight to 19.44 MHz. Each 19.44 MHz clock is distributed to the appro-
priate clock multiplexer (A, B, C, or D).

Transmit Line Interface Summary
The following list summarizes the transmit line interface operations for each STS mode.
I
In quad STS-3/STM-1 and STS-12/STM-4 modes, the transmit line interface receives 8 bits of data from each
OHP block (A, B, C, and D) at 19.44 Mbits/s and 77.76 Mbits/s, respectively. An 8-to-1 parallel-to-serial conver-
sion produces output data at 155.52 Mbits/s for STS-3/STM-1 mode and 622.08 Mbits/s for STS-12/STM-4
mode. For facility loopback, the outputs are multiplexed with the corresponding data from the STS-12/STS-3
(STM-4/STM-1) receive block and sent to four differential LVPECL buffers.
I
In STS-48/STM-16 mode, a 32-bit data word at 77.76 Mbits/s is received from the OHP. Then a 2-to-1 parallel-to-
parallel conversion is performed producing a 16-bit word at 155.52 Mbits/s. In this mode, an external 16:1 data
demultiplexer is required. Facility loopback is not available for the STS-48/STM-16 mode.
I
There is a single clock input, TxCKP/N, in the transmit case. The clock source rates are 622.08 MHz (STS-12/
STM-4), 155.52 MHz (STS-3/STM-1), or 155.52 MHz (STS-48/STM-16).
In the STS-48/STM-16 case, two transmit clock modes are available, contra* and forward clocking. In the contra-
clocking mode, the transmit data is sent out as commanded by TxCKP/N; in addition, an internal PLL must be
activated, core register 0x0010 bit 5, to minimize the phase delay between TxCKP/N and the transmitted data. In
the forward clocking mode, the transmit data and the clock, TxCKQ (used to clock out the data), are sent in par-
allel to the transmit multiplexer.
In STS-12/STM-4 and STS-3/STM-1 modes, the input clock is divided by eight producing the internal clock at
77.76 MHz and 19.44 MHz, respectively. In STS-48/STM-16 mode, the input clock is divided by eight to produce
an internal clock at 77.76 MHz. The CLKDIV pin (H4) controls this division. Table 13 shows the required value of
CLKDIV.
Table 13. Clock Settings for CLKDIV Pin
I
TxFSYNCP/N is an optional external frame sync. This 8 kHz frame sync pulse must be synchronous with
TxCKP/N. It is, at minimum, a one TxCKP/N clock cycle wide pulse that is latched in at the system rate
(622.08 MHz or 155.52 MHz). TOH interface signal RxREF should not be used as a source to TxFSYNCP/N.
I
The active edge of the transmit clock is the positive edge.
I
When TDAT042G5 operates in asynchronous mode (MPMODE = 0), the line block provides the microprocessor
clock to the microprocessor interface block. The CLKDIV pin must be set to ensure that the clock is always
77.76 MHz.
Line interface timing is given in the Interface Timing Specifications section (see Table 168, page 267).
* Contra refers to a type of data transmission whereby a clock signal is received by a register before the register sends data.

Functional Description

SONET Framer
The SONET framer consists of the overhead processor (OHP) and path terminator (PT) blocks. The receive
SONET framer requires 625
s to drop frame after the line input signal is lost. Once a valid receive line input is
restored, the maximum average reframe time (MART) is 250
s.
Overhead Processor (OHP) Block
The OHP block terminates/generates the section and line overhead bytes of the line. The data rate of the TOH
interface is given in Table 14. Timing for the TOH interface is given in the Interface Timing Specifications section
(see Table 172 and Table 173, page 271).
Table 14. R/T TOH Interface Rates
* This STS-48/STM-16 interface is a four-line interface resulting in an effective interface rate
of 82.944 Mbits/s.
All receive transport overhead bytes are output on the RTOH interface for external processing. Transmit transport
overhead bytes can optionally be inserted from the TTOH interface.
The transmit transport overhead bytes can be inserted in one of three ways selected through software provision-
ing: (1) automatically by hardware, (2) via software provisioning, or (3) through the TOAC. Table 15 defines those
overhead bytes that can be inserted via each of the three paths. In some cases, the user has the choice to insert
the byte via software registers or through the TOAC. Superscripts in the table reference these insertion methods
which are described in the footnotes.
Table 15. TOAC Byte Insertion: An STS-3/STM-1 Example
1.Inserted via TOAC, but not part of SONET standard.
2.Inserted via software or automatically via hardware.
3.Inserted via TOAC only.
4.Inserted via software register only.
5.Inserted via TOAC or software register.
6.Inserted via TOAC hardware; should be included in TOAC interface timing.

Functional Description
(continued)
Overhead Processor (OHP) Block
(continued)
The TOAC inserter must insert the first bit of A1 at the TOAC input, TxTOHD[D:A], during the first clock cycle when
TxTOHF = 1. The TOAC has a built-in parity checker. For the parity check, the value of the first inserted bit of A1
must be set to the parity value of the previous frame. The remainder of the inserted bits of the A1, A2 bytes are
ignored by the transmit framer.
Receive OHP
Loss-of-Signal. The loss-of-signal block monitors the incoming scrambled data for the absence of transitions.
When an absence of transitions is detected for a programmable length of time, a loss-of-signal (LOS) is declared.
LOS is cleared when two valid framing patterns are detected, and during the intervening time, no LOS condition is
detected.
Framer. The frame block finds and locks onto the incoming A1 and A2 bytes of the SONET transport overhead.
Loss-of-frame (LOF) is declared when a defect persists for more than 3 ms. LOF is cleared when the defect is
absent for more than 3 ms. To prevent intermittent out-of-frame/in-frame conditions, the 3 ms timer is not reset to
zero until an in-frame (or out-of-frame) condition persists for 3 ms. The framer is also responsible for performing bit
rotations on the incoming data stream to ensure that the rest of the IC receives byte-aligned data.
While in-frame, the A1/A2 framing bytes in each frame are compared against the expected pattern. Out-of-frame
(OOF) is declared when five consecutive frames containing one or more framing pattern errors have been
received.
While out-of-frame, this block will monitor the receive data stream for an occurrence of the framing pattern. When a
framing pattern has been recognized, the framer performs the necessary bit rotation and verifies that an error-free
framing pattern is present in the next frame before declaring in-frame.
J0 Section Trace. The section trace message is extracted and stored in a 16-byte memory for access by software.
The first byte of the message can be provisioned to be either:
I
The byte with the most significant bit (MSB) set high (for SDH), or
I
The byte following a carriage return (0x0D) and line feed (0x0A) sequence (for SONET).
J0 mismatch detection is provided using one of four methods (provisionable via J0MONMODE[A--D][1:0]; see reg-
ister description, page 173).
Descrambler. The descrambler block implements the frame synchronous SONET descrambler with a generating
polynomial of 1 + x
6
+ x
7
. The framing bytes (A1, A2), the section trace bytes (J0), and the growth bytes (Z0) are
not descrambled. The descrambler may be disabled through a software register.

B1 BIP-8 Check. The SBIP block counts section BIP-8 (B1) errors. The SBIP value is calculated over the scram-
bled data of the complete previous frame. The calculated value is compared against the received B1 byte and dif-
ferences (errors) are counted. A theoretical maximum of 64,000 errors may be detected per second. The SBIP
block accumulates these errors in a 16-bit saturating counter. This counter operates in latch and clear mode to
ensure Bellcore and ITU compliance with regard to not missing any events (bit errors). It is intended that this
counter be polled at least once per second so that no error events are missed. Optionally, a maximum of only
one SBIP error per frame can be counted (provisionable via B1BITBLKCNT[A--D]; see register description,
page 174). This causes the error counter to only increment by one when one or more errors are detected.
B2 BIP-N Check. The LBIP block counts line BIP-N errors. The LBIP value is calculated over the incoming frame
and is compared to the received B2 bytes received in the next frame. The errors are counted. Optionally, a maxi-
mum of only one LBIP error per frame can be counted (B2BITBLKCNT[A--D]; see register description, page 174).
This causes the block error counter to only increment by one when one or more errors are detected. A theoretical
maximum of 3,072,000 errors may be detected per second. The LBIP block accumulates these errors in a 22-bit
saturating counter. This counter is operated in latch and clear mode to ensure Bellcore and ITU compliance with
regard to not missing any events (bit errors). It is intended that this counter be polled at least once per second so
that no error events are missed.
BER Check. The OHP block also detects provisionable signal fail (SF) and signal degrade (SD) conditions. The
SF and SD values are provisioned through a group of software registers (SF addresses 0x0452--0x0469,
SD addresses 0x043A--0x0451). The SF alarm can be provisioned for a bit error rate (BER) of between 10
3
to
10
5
; the SD alarm can be provisioned for a bit error rate (BER) of between 10
5
to 10

(see Table 86, page 187).

Figure 6 illustrates the parameters used in determining the bit error detection rate.

Figure 6. Signal Degrade and Failure Parameters for BER
TDAT042G5 provides a method to monitor the BER at the line and path layers. The following explains the algo-
rithm for this method to set and clear the BER. The algorithm for this method is the same for setting and clearing
the BER, the only difference is the programmed values. TDAT042G5 includes two complete sets of identical
counters, one used to determine signal fail (SF) and one used to determine signal degrade (SD). The only differ-
ence between SF and SD is the provisioned values. The same algorithm is used for both the line and path layers of
SONET.
The algorithm uses four sets of counters: labelled Ns (number of frames), L (number of errors), M (number of
errored blocks), and B (total number of blocks). Each of these counters has different values that are provisioned to
either set the BER high or clear the BER indication. The algorithm works by counting blocks, i.e., a preset number
of SONET/SDH frames (Ns). If the number of errors in the block exceeds the provisioned level (L), then the errored
block counter is incremented by 1; otherwise, the number of blocks in error stays at its current level. At this point,
the frame counter and the error counter are reset back to 0 and start counting again. At the end of a preset number
of blocks (B), the count in the errored block counter is compared against a provisioned threshold (M). If the total
number of blocks in error equals or exceeds the provisioned threshold (M), then the BER alarm is raised. If the total
number of blocks in error is less than the provisioned amount (M), then the BER alarm is cleared.
The values used by the counters are determined by the state of the algorithm. If the BER state is low, then the SET
parameters are used. If the BER state is high, then the CLEAR parameters are used.

Functional Description
(continued)
Overhead Processor (OHP) Block
(continued)
Receive OHP (continued)
The OH interface consists of clock, data, and frame. The data and frame signals update on the falling edge of the
clock. The frame pulse is high for the most significant bit (MSB) of the first bit of the frame. Bytes J0, Z0, and F1
(current and previous), K1, K2, and S1 can also be extracted via software registers.
Table 18 shows the ordering of the bytes for the allowed TOAC configurations.
Table 18. TOAC Channel I/O vs. STS Number/Time Slot
The overhead extract block also performs the following functions:
I
Error Monitors. The REI_L block counts remote error indication block errors. The M1 byte is extracted and
counted. This represents the number of LBIP errors detected by the far-end equipment. Optionally, a maximum
of only one REI-L error per frame may be counted (provisionable via M1BITBLKCNT[A--D]; register description,
page 175). This causes the block error counter to only increment by one when one or more errors are detected.
I
Automatic Protection Switch Signaling. The APS block filters the K1 and K2 bytes (automatic protection
switching channel) and stores the validated message in software-accessible registers. The K bytes are validated
after a programmable number of consecutive frames contain identical K1 (and K2[7:3] or K2[7:0]) values. APS
protection switching byte failure is detected within this block when a programmable number of frames have
passed without valid K bytes. The protection switching byte failure is removed upon detection of a programmable
number of frames with identical K1 (and K2[7:3] or K2[7:0]) bytes. The use of K2[7:3] or K2[7:0] is provisionable
via the K1K2_2_OR_1 register bit (see register description, page 169).
I
Line Remote Defect Indicator. Bits 2, 1, and 0 of the K2 byte are monitored for the pattern 110. If this pattern
appears for 3--15 (provisionable by OHP register CNTDK2) consecutive frames, RDI-L is asserted. RDI-L is
removed when any pattern other than 110 is detected for 3--15 (provisionable by OHP register CNTDK2) con-
secutive frames. (See page 171 for register description of CNTDK2[A--D][3:0].)
I
Line Alarm Indication Signal. Bits 6, 7, and 8 of the K2 byte are monitored for the pattern 111. If this pattern
appears for 3--15 (provisionable by OHP register CNTDK2) consecutive frames, AIS-L is asserted. AIS-L is
removed when any pattern other than 111 is detected for 3--15 (provisionable by OHP register CNTDK2) con-
secutive frames. (See page 171 for register description of CNTDK2[A--D][3:0].)

I
Rx Synchronization Message. The S1 block filters the synchronization message (S1) byte and stores the vali-
dated message in a software-accessible register. The synchronization message will be validated if a programma-
ble number (in OHP register CNTDS1) of consecutive frames contain identical S1 values. An inconsistent
synchronization message alarm will be reported if a provisional number (by OHP register CNTDS1FRAME) of
consecutive frames pass without a validated message occurring. (See page 172 for register descriptions of
CNTDS1[A--D][3:0] and CNTDS1FRAME [A--D][3:0].)
I
F1 User Channel. The F1 byte is extracted by the OHP. The F1 user channel is monitored for change of state
using OHP registers 0x0402, 0x0404, 0x0406, 0x0408 (see register map, page 116). The previous and current
F1 values are stored in F1DMON1[A--D][7:0] and F1DMON0[A--D][7:0], respectively (see page 122 for register
map, page 190 for register descriptions).
I
DCC and Orderwire Bytes. The data communication channel (D1--D3, D4--D12) and orderwire bytes (E1, E2)
can only be extracted via the TOAC.

Support for ATM/Packet-Over-Fiber. The transport overhead must be bypassed when operating in data-over-
fiber mode. In this mode, the TOH_BYPASS and ROH_BYPASS register bits must be set to 1. No overhead
insertion/extraction is done when in bypass mode.
Transmit OHP
Overhead Insertion. Some transport overhead (TOH) bytes can optionally be inserted via the TxTOH interface
and inserted into the TOH bytes (see Table 15, page 53). Certain bytes can be either inserted from values stored in
registers or automatically generated. The TxTOH interface controls the insertion mechanism. Software insertion
takes precedence over TOAC insertion. The number of bits received are as follows:
I
STS-3/STM-1: 5,184,000 bits/s per interface
I
STS-12/STM-4: 20,736,000 bits/s per interface
I
STS-48/STM-16: 82,944,000 bits/s (over 4 serial lines (20,736 kbits/s each))
S1 Synchronization Message. The S1 block controls the insertion of the S1 byte. The byte ordering is the same
as the RxTOAC and is shown in Table 18 (see pa ge59). The S1 byte can be provisioned to come from the TxTOH
interface or from a software-settable register. Control for message insertion is from software control register
TS1INS[A--D] (see register description, page 179 and page 183).
K1K2 APS Signaling. The APS block controls the insertion of the K bytes based on software provisioned K bytes,
and alarm conditions (AIS-L, RDI-L). Inconsistent APS bytes can be inserted via register provisioning by
TAPSBABBLEINS[A--D] (see register description, page 178 and page 183).
RDI_L Generation. The following six alarms contribute to RDI_L generation: LOF, OOF, LOS, LOC, AIS_L, and
SF. They can be inhibited from contributing to RDI-L via transmit control registers (addresses 0x042F, 0x0431,
0x0433, 0x0435; see register description, page 180).

Path Terminator (PT) Block
The path terminator performs path overhead (POH) termination and extracts the payload for further processing by
the downstream circuitry. The path terminator block interprets the incoming H1/H2 pointer of each incoming STS
channel. The pointer interpreter supports up to four channels and performs path overhead termination on each
channel. Each channel may be either an STS-1, STS-3c, STS-6c, STS-9c, . . . , STS-45c, or STS-48c.
The pointer is validated according to Bellcore and ITU specifications. The H1/H2 pointers are used to determine
the location of the first path overhead (POH) byte (J1). The pointer interpreter consists of a finite state machine
(FSM) with four steady states. These states are defined as follows:
I
Normal state
I
Loss-of-pointer (LOP)
I
Alarm indication signal (AIS)
I
Concatenation
The transition between states will require several consecutive events to protect against transient conditions caused
by bit errors during high BER conditions. The state machine is shown below in Figure 7.

The PT block monitors for the following conditions and takes appropriate actions:
I
Pointer Increment. TDAT042G5 uses an 11-bit counter to count the number of pointer increments and updates
the associated counter holding register on the occurrence of PMRST (RPI_INC[A--D][10:0]; see register
description, page 198). A pointer increment can occur when in the normal pointer mode. The following two meth-
ods can be used to determine if the pointer increment operation should be performed: 6-of-10 or 8-of-10 majority
matching (selectable via software provisioning of register RINCDEC_6OR8MAJ [A--D]; see register description,
page 200).

I
Pointer Decrement. TDAT042G5 uses an 11-bit counter to count the number of pointer decrements and
updates the associated counter holding register on the occurrence of PMRST (RPI_DEC[A--D][10:0]; see regis-
ter description, page 198). A pointer decrement can occur when in the normal pointer mode. The following two
methods can be used to determine if the pointer decrement operation should be performed: 6-of-10 or 8-of-10
majority matching (selectable via software provisioning of register RINCDEC_6OR8MAJ [A--D]; see register
description, page 200).
I
Loss-of-Pointer. LOP-P is declared as shown in the above state diagram. In an LOP-P state, none of the path
overhead bytes are extracted.
I
AIS-P. The AIS-P is declared when the H1 and H2 bytes are set to all ones. In an AIS-P state, none of the path
overhead bytes are extracted.
I
Concatenated Pointer. A concatenated pointer is detected when the new data flag is set and the pointer offset
value is all ones.
I
New Pointer. TDAT042G5 uses a 13-bit counter to count the number of new data flags that occur and updates
the associated counter holding register on the occurrence of PMRST (RNDFCNT[A--D][12:0]; see register
description, page 198). TDAT042G5 uses a 3-of-4 majority voting scheme to determine if the new data flag is
set. Valid new data flags occur when the NDF bits are either 1001, 0001, 1101, 1011, or 1000.
I
Normal Pointer. A normal pointer occurs when all of the following conditions are true simultaneously:
1. NDF is not set (NDF bits are either 0110, 0111, 0100, or 0010),
2. There is no invalid pointer value,
3. There is a valid offset (0 to 782)
I
Invalid Pointer. An invalid pointer is declared when neither a new data flag nor a normal pointer is detected.
SPE Terminate
Receive Path Trace. The path trace message is extracted and stored in a 16-byte (SDH) or 64-byte (SONET)
memory for access by software. The first byte of the message can be provisioned to be either of the following:
I
For SDH mode, the byte with the most significant bit (MSB) set high (for SDH)
I
For SONET mode, the byte following a carriage return (0x0D) and line feed (0x0A) sequence
The framing can also be disabled.
Receive Error Monitor. The PBIP block counts path BIP-8 errors. A theoretical maximum of 64,000 errors may be
detected per second. The PBIP block accumulates these errors in a 16-bit saturating counter. This counter is oper-
ated in latch and clear mode to ensure Bellcore and ITU compliance with regard to not missing any events (bit
errors). It is intended that this counter be polled at least once per second in order that no error events are missed.
The REI_P block counts remote error indication block errors.

Receive Signal Label. The C2 block will extract and validate the signal label byte (C2) and store it in a software-
accessible register. The signal label is updated when a provisionable number of consecutive detections of a new
C2 value occur (CNTDC2[A--D][3:0]; see register description, page 204). All monitoring is disabled when the
pointer is in an LOP-P or an AIS-P state. Commonly used values of C2 with their signal labels are listed below in
Table 19.
Table 19. Types of Signal Labels
Any value of C2 may be provisioned. If the provisioned value is not matched by the detected value, then data is not
passed to the DE. If the provisioned value does match the detected value, then data is passed to the DE.
TDAT042G5 will detect unequipped payloads (UNEQ-P) when a provisionable number of consecutive monitored
C2 bytes match the 0x00 unequipped STS SPE state. TDAT042G5 will detect mismatched payloads (PLM-P)
when a provisionable number of consecutive monitored C2 bytes do not match the provisioned expected payload
label (RC2EXPVAL[7:0]; see register description, page 205).
Receive Path Status. The G1 block extracts the path remote error indication (REI-P) bits of G1[7:4] and accumu-
lates the REI-P errors in a 16-bit saturating counter. This counter is operated in latch and clear mode to ensure
Bellcore and ITU compliance. It is intended that this counter be polled at least once per second in order that no
error events are missed.
RDI-P. This block will also validate the path remote defect indication (RDI-P) bits and store the result in a software-
accessible register. The receive path can monitor remote defect indications in either enhanced or single bit RDI-P
modes (provisionable via software bit RDIPMON_ENH_OR1B [A--D]; see register description, page 200). The
interpretation of the G1 byte is as follows.

Z5/N1, Z4/K4, Z3/F3, H4, F2 Monitoring. TDAT042G5 monitors the F2 user channel byte, the H4 VT multiframe
indicator byte, Z3/F3 growth/user byte, Z4/K4 growth/APS path byte, and the Z5/N1 tandem connection byte.
These bytes are stored in software registers. These registers are updated when a provisionable number of detec-
tions of new values occur on the associated incoming byte. All monitoring is disabled when the pointer is in an
LOP-P or an AIS-P state.
Signal Failure and Signal Degrade Monitoring. The path overhead processor also detects/clears provisionable
signal fail (SF) and signal degrade (SD) conditions. The SF and SD values are provisionable through a group of
software registers in the PT register map. The provisioning is the same as that shown in Table 16, page 57 of the
Overhead Processor (OHP) Block section.
SPE Generate
Transmit Pointer Generation. The pointer generation block generates the outgoing H1 and H2 pointer values.
Each of the four PT channels can generate one normal (valid) pointer. Therefore, in STS-3/STM-1 and STS-12/
STM-4 modes, only one normal pointer (and only one SPE) may be inserted into the transmitted SONET/SDH
frame. In STS-48/STM-12 mode, all four PT channels are used. Therefore, up to four normal pointers (and four
SPEs) may be inserted into the transmitted SONET/SDH frame.
When inserting concatenated frames, only the first H1 and H2 bytes will contain a valid pointer value. The remain-
ing H1 and H2 bytes of the channel will be set to indicate concatenation. The remaining unequipped channels will
have their H1 and H2 pointers set to a fixed pointer value.
For proper pointer generation, the appropriate values must be provisioned in the H-byte transmit state register
THx_STATE (see register description, page 203).
The following examples illustrate how the device may be configured to transmit various sub-rates and concate-
nated payloads. Each block in the following diagrams represents one STS-1 frame. Figure 8 illustrates how to pro-
vision the THx_STATE registers to transmit an STS-48c frame within an STS-48 signal. In this example, the pointer
to the first STS-1 is provisioned as a normal pointer value while the pointers to the remaining STS-1 signals are
provisioned as concatenated pointers. Figure 9 illustrates how to provision the THx_STATE registers to transmit
four STS-12c frames within an STS-48 signal. The concatenated STS-Mc frames that may be mapped into STS-N
signals (where M
N) are restricted to those listed in Table 22 (see page 68).

The general rule for mapping STS-Mc frames in STS-N signals (M
N) is that the TDAT042G5 can have a maxi-
mum of four normal pointers in STS-48 mode. For M
12, the valid starting locations for mapping into an STS-48
signal are 1, 13, 25, and 37. For M >12, only one normal pointer is permitted and it must start at the first location
(the first STS-1). The TDAT042G5 allows only one normal pointer in STS-3 or STS-12 modes. The only valid start-
ing location for mapping concatenated frames into an STS-3 or STS-12 signal is 1.

BIP-8. The PBIP block calculates the B3 value according to Bellcore and ITU standards. Insertion of PBIP errors is
possible through the use of a software control register.
REI Generation. The REI_P block controls the insertion of the remote error indication block error count. The
received PBIP error counts are inserted into the path status (G1) byte.
RDI-P Generation. The transmit path can insert remote defect indications using either single-bit or enhanced
RDI-P modes (provisionable via software register bit TRDIP_ENH_OR1B[A--D]; see register description, page
202). The highest to lowest priority of the defect code insertion is as follows:
1. AIS-P, LOP-P (applies only to the single-bit version of RDI-P),
2. UNEQ-P,
3. PLM-P, LCD-P,
4. No defects
TIM-P can be inserted using software through TRDIPSINS (registers 0x0AAA, 0x0AB2, 0x0ABA, or 0x0AC2,
bits 15--11; see register description, page 201). The LCD-P defect is observed in the data engine and passed to
the pointer block for transmission. Each particular defect can be inhibited from contributing to the transmitted
RDI-P insertion value via software registers 0x0AAA, 0x0AB2, 0x0ABA, and 0x0AC2. RDI_P can either be inserted
by software or automatically through hardware.
Z5/N1, Z4/K4, Z3/F3, H4, F2 Insertion. TDAT042G5 inserts the F2 user channel byte, the H4 VT multiframe indi-
cator byte, Z3/F3 growth/user byte, Z4/K4 growth/APS path byte, and the Z5/N1 tandem connection byte via soft-
ware provisioning.
Error Insertion Mechanisms. TDAT042G5 provides a method to inject via software REI-P
(TREIPERRINS[A--D]) and B3 (TB3ERRINS[A--D]) errors into the transmitted SONET frame (see register
descriptions, page 202).
Insertion of J1, F2, C2, Z3, H4, Z4, Z5, SS Values. TDAT042G5 provides paged provisionable registers to insert
the path overhead bytes into the outgoing SONET frame. The paging is done by first writing to the page provision-
ing register at location 0x0AC6 to set the port number and time slot to be provisioned, and then writing to the
appropriate insertion registers. Available time-slot values for TDAT042G5 are time slot 1 for STS-48c mode; time
slots 1, 2, 3, and 4 for STS-48 consisting of four STS-Mc (M
12) signals; and time slot 1 for quad STS-12c and
quad STS-3c modes (ports A, B, C, and D configured for quad STS-3c and quad STS-12c).

Data Engine (DE) Block
The DE block processes ATM, SDL, PPP, and HDLC cells/packets at rates up to 2.488 Gbits/s. The DE block
behaves like four independent logical data channels, one for each of the four STS-12/STM-4 or STS-3/STM-1
channels, or like a separate single channel for STS-48/STM-16. The following description is for each one of these
data engines. Each of the functional elements to be described are independently provisioned.
The data engine supports both ATM cells and packet data formats.
I
The ATM processor functions with 52-byte, 53-byte, and 56-byte ATM cells.
I
The packet processor has three packet modes: HDLC, CRC, and PPP. All three modes use HDLC framing, i.e.,
0x7E delineates the packets. In HDLC mode, the 0x7E framing bytes are inserted or detected by the data
engine. In the CRC mode, a user-selectable 16-bit or 32-bit CRC word is appended or detected at the end of the
packet. The PPP mode places or detects a PPP header on the front of the packet as well as uses the CRC word.
The block diagram for the data engine is shown in Figure 13.

Receive Data Engine
Receive Sequencer. The receive sequencer demaps SONET framing to four logical channels, performs the phys-
ical channel byte alignment and packing, and performs appropriate payload clock domain transfer. The receive
sequencer must be provisioned properly for correct operation. There are six registers that are fixed for each partic-
ular mode of operation (STS-3/STM-1, STS-12/STM-4, or STS-48/STM-16) and must not be modified
(SEQ_CTRL, INIT_CNTS, OH_MARKER_LO, OH_MARKER_HI, SOH_MARKER_LO, SOH_MARKER_HI). See
the register descriptions for details, page 214. Also, the appropriate time slots must be provisioned for the rate of
the payload expected for each channel. This is done via the registers Rx_TS[1--12] (see register descriptions,
page 219). An example of how to configure this for STS-48c mode is shown in the section on configuring the trans-
mit/receive sequencer (see Transmit Data Engine section, page 78).
ATM Cell Processor. The cell processor performs ATM cell delineation using the ATM header error correction
(HEC) field found in the cell header. The HEC is a CRC-8 calculation over the first four octets (total of 32 bits) of
the ATM cell header. If the TDAT042G5 is in bit-synchronous mode (data is not byte-aligned), 32 separate HEC
calculations are performed to delineate an ATM cell. If the TDAT042G5 is in byte-synchronous mode (data is byte-
aligned), four separate HEC calculations are performed to delineate an ATM cell. An alpha-delta counter is used to
track the processor's ability to frame the ATM cells consistently. When a certain level of confidence is reached
(defined by the programmable delta counter threshold), the frame is declared in sync state, and data is passed to
subsequent blocks. If the framer is unable to frame ATM cells over a few cell periods (defined by the programma-
ble delta counter threshold), the framer resumes hunt state.
In SONET mode, the processor performs optional X
43
unscrambling of the payload. Because the X
43
scrambler is
self-synchronizing, the framer needs no assistance from the data in order to synchronize the scrambler. The
TDAT042G5 also supports an X
31
scrambler, compliant with I.432, which is mainly used for packet-over-fiber
applications. The state diagram for the X
31
scrambler is shown in Figure 14 on page 72. The X
31
scrambler uses
an x
31
+ x
28
+ 1 polynomial to scramble the data. Unlike the X
43
scrambler, the X
31
scrambler does not self-
synchronize based upon the data it receives. Thus, one-bit samples of the scrambler output are sent on the trans-
mit side and compared with the scrambler samples on the receive side every 212 bits. If the samples do not match,
the receive-side scrambler is adjusted to converge with the transmit-side scrambler. This process continues until a
certain level of confidence in the scrambler synchronization is achieved. In the X
31
mode, the ATM cell processor
does not send out any output until both the framer and the scrambler are synchronized, whereas in X
31
mode, only
the framer needs to be synchronized.
Idle ATM cells, which contain no real data, can be either left in or removed from the bit stream. The idle cell header
description can be configured, though it is set to a default value (0x00000001). ATM cells can also be filtered if the
header contents match a provisioned match register after masking with a provisionable mask register. This allows
filtering based on the contents of the GFC, PTI, and CLP fields of the header. Optionally, ATM cells may be
dropped if uncorrectable HEC errors are detected. Incoming single-bit ATM header errors can be corrected and the
cells may be passed through or dropped, depending on the software configuration.
The data engine processes only standard 53-byte ATM cells. However, the UTOPIA block processes 52-byte, 53-
byte, 54-byte, and 56-byte cells, and interfaces these to the data engine. (See UTOPIA (UT) Interface Block,
page 86, for details).

SDL Frame Processor. The SDL frame processor consists of an SDL framer, which detects the start of SDL pack-
ets, and an (optional) X
48
unscrambler, which is used to unscramble payload data. SDL packets can also arrive
unscrambled, in which case the unscrambler is disabled. The SDL frame processor can frame packets in SDL form
which contain a data length between 4 and 65,535 bytes.
The SDL framer uses a CRC-16 check upon 2 bytes sequences used to determine packet length in order to frame
SDL packets. Since the framer is designed to support data that is not byte-aligned, 32 separate framers may be
used to search for the CRC-16 pattern. If the data is byte-synchronized, only four framers are needed. A confi-
dence counter is used to gauge the framer's ability to frame SDL packets consistently. When the confidence
counters reaches a certain level (defined by the programmable SDL delta counter register), the framer is in sync
state. Single-bit error correction for the SDL headers is also supported. Shown below in Figure 15 is the general
structure of the SDL packets. In this figure, there is no interpacket fill.

Interpacket fill separating packets always contains a multiple of 4 bytes. The SDL framer is able to detect inter-
packet fill since its value is fixed. (It has 4 bytes equal to 0x0000000, i.e., a packet length of 0x0000 with a CRC-16
of 0x0000.) Since the framer knows the length of a particular packet and can detect interpacket fill, it will predict the
start of the next frame and frame on it. The SDL frame processor supports SDL and SDL CRC modes. When oper-
ating in SDL CRC mode, a 2-byte or 4-byte CRC for the packet payload is attached to the end of the packet pay-
load prior to the next packet length. When operating in SDL mode, there is no 2-byte or 4-byte CRC for the packet
payload.
The SDL frame processor supports X
48
scrambling of the packet payload, which is accomplished by using a primi-
tive polynomial of x
48
+ x
28
+ x
27
+ x + 1. The X
48
scrambler is not self-synchronizing. Thus, the side transmitting
SDL packets will periodically send its 48-bit scrambler state within the data stream such that the receive side can
synchronize its scrambler. Whenever the SDL frame processor receives a scrambler state, it is immediately put
into sync state, which allows it to send data out. Upon receiving additional scrambler states, the scrambler will
compare its own state with the state received. If the scrambler states match, then the scrambler remains in sync
state. However, if there is a mismatch, the scrambler is put into postsync state. In postsync state, if an additional
scrambler state mismatch occurs, the X
48
scrambler is resynchronized with the scrambler state it has received.
The SDL frame processor detects scrambler state data since the packet length field of 0x001 and the length of
time separating scrambler state transmissions is programmable. Single-bit error correction for the SDL scrambler
state is incorporated within the TDAT042G5.
Both the SDL framer and the X
48
scrambler must be synchronized before the SDL frame processor will send data.
Besides the SDL scrambler state being transmitted, the SDL framer will also extract special A and B messages
used by the upstream device to send link layer 1 messages to the downstream hardware. The packet length field
used to detect A and B messages are 0x0002 and 0x0003, respectively.
In addition to scrambling the data, the SDL data stream coming into the SDL frame processor is dc balanced with
the 32-bit value 0xB6AB31E0.
Table 23 below is used to describe the packet length field.
Table 23. Packet Length Field
Pre-descrambler. The pre-descrambler block descrambles the payload using a self-synchronous descrambler

. For ATM cell traffic, only the 48-byte cell payload (and not the cell over-
head) is descrambled. For HDLC and PPP packets, the entire frame (including header and trailer) is descrambled.
Predescrambling, post-descrambling, or no descrambling may be selected through a provisionable register.

HDLC Framer. The packet processor frame aligns to HDLC packets using the HDLC flag character (0x7E). Flags
are also used to fill interpacket spaces. The flags are removed and control escape destuffing is performed. The
control escape character (0x7D) is searched for and when it is found, the control escape character is removed, i.e.,
0x7D5D is unescaped to 0x7D and 0x7D5E is unescaped to 0x7E. If dry mode is enabled, then 0x7D20 is unes-
caped to a value of 0x00, which represents dry data (FIFO underflow in the middle of a packet). Any other unes-
caped sequence of 0x7D results in an errored packet.
CRC Check. An optional CRC-ITU or CRC-32 calculation on the whole POS frame is performed after byte destuff-
ing and data descrambling. The CRC-ITU generating polynomial is 1 + x

. The computation over
the whole packet, including the FCS field, should result in all zeros. A different value indicates an error. Packets
with FCS errors are marked as such and are discarded. CRC field stripping is optional. Both normal and reversed
CRC modes are supported.
Post-descrambler. The descrambler block descrambles the payload using a self-synchronous descrambler with a
generator polynomial of 1 + x
43
. For ATM cell traffic, this block is bypassed. For HDLC frames, the entire frame
(including header and trailer) is descrambled. The descrambler may be disabled through the use of a software reg-
ister.

PPP Header Detach. The PPP detach function matches the PPP header (corresponding to the first 4 bytes of the
PPP uncompressed frame or first 2 bytes of the PPP compressed frame) to a set of fixed or provisionable values
for each channel and outputs frames in accordance with payload control register settings. The address and control
field bytes are assumed to be 0xFF03. The block supports two fixed protocol fields (0x0021 corresponding to the
IP protocol field, and 0x8021 corresponding to the IP control protocol). Additionally, 12 provisionable registers,
PPP_Rx_HDR [0--11][15:0] (addresses 0x10F0--0x10FB), are supported on-chip to allow a large number of pro-
tocols to be recognized in the receive (ingress) data path of the chip.
The PPP detach function supports compressed or uncompressed header fields, optionally matching two fixed (one
corresponding to IP protocol) 16-bit protocol fields. This optional PPP header check allows PPP (normal or com-
pressed (i.e., no FF03)) to be checked and the header optionally stripped. Packets that fail to match one of the pro-
visioned headers or the two default headers can optionally be discarded. This function supports optionally
matching 12 programmable 16-bit protocol fields. The PPP detach function provides mismatched PPP header
count on a per-channel basis through four 28-bit counters, PM_MHC_[0--3][27:0] (addresses 0x1118--0x111F).
The function can optionally discard frames if header fields do not match on a per-channel basis. It can also option-
ally strip header fields only if they do match on a per-channel basis.
A PPP packet has the following two formats:
5-9642 (F)
* TDAT042G5 is verified to handle packets of up to 64 Kbytes. Larger packets may be processed, but no upper bound or packet size
has been determined. Packets of less than 4 bytes are discarded by the DE.
Figure 16. Uncompressed and Compressed PPP Packets
Each channel has a 16-bit register, PPP_Rx_CHK_CH [0--3][15:0] (addresses 0x10FC--0x10FF), that can be
provisioned.
If the header bytes do not match and payload control bit 7 = 0, the entire PPP packet is discarded for a given chan-
nel. Otherwise, if the header bytes do not match and payload control bit 7 = 1, the PPP packet is marked as bad
and not discarded for a given channel.
If payload control bit 6 = 0, the header is stripped, provided it matches a provisionable value; otherwise, it is left on
for a given channel.

counts for PPP packets with various header errors/mismatches as provisioned in the registers.
I
CRC Field. The CRC bad packet counter, PM_BPC_n (n = 0, 1, 2, 3), increments if a CRC error is found in
channel n.
Each PPP packet not counted as a bad packet in PM_MHC_n (n = 0, 1, 2, 3) counter or PM_BPC_n counter incre-
ments the PPP good packet counter, PM_GPC_n (n = 0, 1, 2, 3), for channel n. (See register descriptions,
page 241.)
Note that each channel only has a single pair of good and bad packet counters.
Transmit Data Engine
ATM Cell Inserter. The ATM cell inserter provides X
43
or X
31
scrambling of the payload for transport of ATM cells
over SONET. X
31
scrambling is suitable for the transport of ATM cells over fiber where bit-level cell delineation is
required. The state diagram for the X
31
scrambler is shown in Figure 14, page72. The ATM cell inserter will gener-
ate idle cells/bytes to fill the SONET/SDH payload when cells/packets are not available in the transmit direction
FIFO of the UTOPIA block. For ATM cells, the GFC, PTI, and CLP fields of the idle cell header and the idle cell pay-
load are provisionable via software registers. The idle generator generates idle cells/bytes to fill the SONET/SDH
payload when cells/packets are not available in the transmit FIFO. Idle cell HCS is automatically calculated and
inserted.
Header Check Sequence (HCS) Generator. The HCS generator performs a CRC-8 calculation over the first four
header octets of the ATM cell. The generator inserts the result into the fifth octet of the ATM header.
SDL Frame Inserter. The SDL inserter performs SDL frame generation and X
48
scrambling of the payload field.
An optional CRC-16/32 field can be attached (SDL-CRC mode) and is calculated over the payload. The SDL
inserter also periodically transmits scrambler state updates through a special 6-byte message. The time between
scrambler state updates can be provisioned by software using register SDLFI_INT (see register description, page
250). The packet length header of scrambler state updates is the 16-bit word, 0x0001. Special A and B messages
can be software-provisioned to send link layer 1 messages to downstream hardware. The packet length headers
for the special A and B messages are 0x0002 and 0x0003, respectively.

Prescrambler. The prescrambler block optionally scrambles the payload using a self-synchronizing scrambler with
a generator polynomial of 1 + x
43
for HDLC and PPP packets. For HDLC frames, the entire frame, including
header and trailer, is scrambled; however, HDLC flags are not scrambled. The scrambler may be disabled through
the use of a software register. This scrambler removes excessive 0x7D and 0x7E bytes. For ATM cell and SDL
packet traffic, this block is not used. (By randomizing the data, the scrambler prevents malicious use of the channel
due to escaping 7D and 7E sequences.)
CRC-16/-32 Generator. An optional CRC-16/-32 generator on the whole packet frame can be performed. The gen-
erating polynomial for CRC-16 is 1+ x

HDLC Inserter. The HDLC framer provides frame check sequence (FCS) generation and insertion using either the
CRC-ITU or CRC-32 generation polynomials. After optional CRC generation, the HDLC framer performs control
escape (0x7D) stuffing, flag character (0x7E) or abort character (0x7D7E) insertion, and dry mode insertion
(0x7D20, where the last two bytes (the 20 bytes of the default value of 0x7D20) are provisionable).
Postscrambler. The postscrambler block optionally scrambles the payload using a self-synchronizing scrambler
with a generator polynomial of 1 + x
43
for HDLC and PPP packets, in accordance with RFC1619. For HDLC and
PPP packets, the entire frame, including header and trailer, is scrambled. The scrambler may be disabled through
the use of a software register. For ATM cell and SDL packet traffic, this block is not used.*
PPP Header Attach. The PPP attach function inserts the provisionable 4-byte PPP header if payload control
bit 7 = 1 (addresses 0x10E0--0x10E3). The first and second bytes are set to 0xFF03, and the third and fourth
bytes are set to a value defined by a software register in PPP_Tx_CHAN[0--3] (see register descriptions,
page 234).
If payload control bit 7 = 0 (addresses 0x10E0--0x10E3) (compressed PPP header mode), only the two provision-
able bytes defined by the software register PPP_Tx_CHAN[0--3] can be attached. Note that there is only one soft-
ware register-defined protocol value for each channel.
The PPP attach function provides good packet count on a per-channel basis through four 28-bit counters,
PM_GPC_TX_[0--3] [27:0] (addresses 0x1128--112F).
* The ATM and SDL framer inserters have their own dedicated scramblers.

Tx Sequencer. The transmit sequencer maps logical channels into SONET frames, and must be provisioned prop-
erly for correct operation. The appropriate time slots must be provisioned for the rate of the payload expected for
each channel. This is done via the registers Tx_TS[1--12] (see register descriptions, page 215).
TDAT042G5 provides 12 time slots and four channels to define how data is mapped into the 48 synchronous trans-
port signals (STS-1) of an STS-48 frame or into the 12/3 STS signals of an STS-12/3 SONET frame.
Figure 17 illustrates the mapping of the 48 STS-1 signals into an STS-48 signal and their assigned time slots. Each
STS-1 block in the figure represents a byte of data for the specific STS-1 signal. The STS signals within the 12 time
slots are ordered such that the SONET multiplexing requirements of lower rate signals into higher rate signals are
satisfied. A value of 0x4 indicates that valid data is contained in the specific byte (STS) and the data is being
received/transmitted from/to channel 0.

The multiplexing rules of SONET are illustrated in Figure 19, and are shown for the case of two-stage byte inter-
leaving of 12 STS-1 signals into an STS-12 signal. The values provisioned in the time-slot registers should obey
the SONET multiplexing rules. In Figure 18, time slots 1 through 12 of channel A represent the interleaved bytes of
the multiplexed STS-12 signal being received/transmitted in logical channel 0 (0x4). Channels B, C, and D are con-
figured similarly; however, data is being received/transmitted from logical channels 1, 2, and 3, respectively.

Figure 20 illustrates the configuration of the time-slot registers for four independent STS-3 signals. In this case,
there are three STS-1 signals that comprise each STS-3 signal. Since there are 12 time slots and only three are
actually required, the values in time slots 4--12 can be repetitively configured as shown in the figure or can be
configured as invalid, i.e., 0x0, 0x1, 0x2, and 0x3 for channels A, B, C, and D, respectively.

Performance Monitoring
This block contains several cell/packet counters for receive/transmit data traffic. Two 28-bit saturating counters
count the number of good packets/cells that are sent out and received by the enhanced UTOPIA interface. There
are 28-bit counters used to count the number of corrected ATM HCS single bit errors, HDLC invalid sequences,
and SDL corrected headers. Also, 28-bit counters are used to count the number of uncorrectable HCS errored
ATM cells (discarded cells), HDLC short packets, SDL errored headers, packets with bad CRC checks, and mis-
matched PPP headers. These counters are operated in latch and clear mode (using PMRST) to ensure GR-256
standards compliance. It is intended that these counters be polled at least once per second so that no error events
are missed.

Over-Fiber Modes
In addition to the support of the normal SONET/SDH modes for different payload types such as HDLC, PPP, ATM
(X
43
or X
31
), and SDL as shown in Figure 2 on pa ge45, this device is capable of supporting the over-fiber modes
for two payload types, SDL or ATM (X
31
). In the over-fiber mode, a 3% payload increase can be realized because
the data stream contains no SONET/SDH overhead bytes.
In the over-fiber modes, it is possible to utilize the whole bandwidth (155 Mbits/s for OC-3, 622 Mbits/s for OC-12,
or 2.5 Gbits/s for OC-48) of the optical fiber for SDL packets or ATM cells.
As can be seen in Figure 21, for over-fiber modes the device is provisioned as follows:
I
The line termination (OHP) and path termination (PT) blocks of the device need to be provisioned in the
passthrough mode.
I
The payload termination (DE) block needs to be set to the bit synchronization mode in the payload control regis-
ter.
I
The transparent mode in the transmit and receive sequencers (addresses 0x102E and 0x102F; see register
description, page 223).
I
Bit 12 of the mode register (address 0x0010) needs to be set to 0 so that the received clock drives the entire
receive data path. In this way, there is no need to cross the clock domain boundary. As a result, only a single
channel is allowed for OC-3, OC-12, or OC-48 when the device is operated in the over-fiber modes. In contrast,
the device is capable of supporting four OC-3/OC-12 channels or one OC-8 channel in the SONET/SDH modes.

Transparent Payload Mode
The transparent payload mode in the payload termination data engine (DE) block is one of seven basic payload
type modes in the payload control registers and allows data to pass directly through the DE. In this mode, no fram-
ing is done on the data, and the data in the SONET frame is treated as raw data. The transparent payload mode
basically disables all the functions of the framers. In contrast, the transparent mode of the sequencer (over-fiber
mode) disables the conversion function of the sequencer between the SONET/SDH framing structure and the log-
ical channel structure.
In the transparent payload mode, the data engine processes the entire payload as a single packet with no J1 byte
or other POH. An RxSOP is generated on the UTOPIA interface on the first byte following the J1 byte. The last
byte of payload occurs at an RxEOP.
If the device is set in both the transparent payload mode in the payload control registers and the transparent mode
in the sequencer, then the whole SONET/SDH frame (overhead bytes will be overwritten with zeros) will appear at
the receive UTOPIA interface as one packet. At the transmit UTOPIA side, the whole SONET/SDH frame needs to
be supplied.
Transparent Receive Mode Control. In receiving from the line, provisioning must specify the time slot and
SONET frame byte location where the last byte in the packet will occur. The following registers are used to indicate
this location.
I
Rx_CHCD_FM (address 0x1030; see register description, page 224) specifies the time slot where the last byte
of a packet exists in channels C and D.
I
Rx_CHAB_FM (address 0x1031; see register description, page 224) specifies the time slot where the last byte
of a packet exists in channels A and B.
I
Rx_CELLA_FM (address 0x1032), Rx_CELLB_FM (address 0x1033), Rx_CELLC_FM (address 0x1034), and
Rx_CELLD_FM (address 0x1035) specify in which SONET location (0 to 809) the last byte in a packet exists in
channel A, B, C, or D, respectively. (See register descriptions, page 225.)
In the case where the location of the last byte in the frame is not known, the last byte should be provisioned for
location 809 and time slot 12, and external UTOPIA hardware must perform packet delineation on the data
stream.
Transparent Transmit Mode Control. In transmitting to the line, provisioning must specify the time slot and
SONET frame alignment. This is done through Tx_TRANS_CTRL (address 0x102F; see register description,
page 223) used in conjunction with Tx_TS[1--12] (addresses 0x1016--0x1021; see register descriptions,
page 215).

UTOPIA (UT) Interface Block
The UT core provides buffering and UTOPIA interface functionality. This enhanced UTOPIA interface will pass U2,
U2+, U3, and U3+ protocols. In the receive direction, data is buffered from the line side, and sent out of the device
via a UTOPIA/packet-over-SONET-PHY interface. In the transmit direction, data is received by the device via a
UTOPIA/packet-over-SONET-PHY interface, and buffered before being sent to the line side. Data that is sent or
received can be either packet or ATM traffic, and is configurable on a per-channel basis. The UTOPIA slave inter-
face is designed to accommodate back-to-back ATM cell and packet data transfers in point-to-point or multi-PHY
modes.
Level-2 physical interfaces (transmit and receive) support four logical data channels as shown in Figure 22. Each
of these interfaces is independently configurable for cell or packet transfers, and can support up to STS-12/STM-4
bandwidth. Optionally, two of the interfaces, specifically A and B, can be grouped together to support a 32-bit
UTOPIA level-3 interface supporting up to STS-48/STM-16 of bandwidth. The aggregate traffic that can be carried
over these interfaces is limited to STS-48/STM-16 bandwidth.
In addition to operating as separate point-to-point streams, MPHY capabilities for up to four channels can be pro-
vided from the A interface in either 16-bit or 32-bit modes. For example, when operating as a 32-bit interface, the A
interface can support either a single STS-48c channel or four STS-12c channels. As a 16-bit interface, the MPHY
interface can support either a single STS-12c channel or four STS-3c channels.
Since each channel can be configured independently, each one can carry different traffic types at different rates,
provided that the capabilities of the active interfaces and the data engine are not exceeded.
There are two basic data paths: receive side, defined to be data going from the line side to the UTOPIA side, and
transmit side, defined to be data going from the UTOPIA side to the line side as shown in Figure 22.

Enhanced refers to the extensions that have been added to support packet transfers. These extensions are indica-
tions of the following: (1) an end of packet (TxEOP/RxEOP), (2) the byte on which packet ends in last word (TxSZ/
RxSZ), and (3) the signal to abort a packet early (TxERR/RxERR). An abort occurs, for example, if the check sum
at the end of a packet is bad, or the end of a packet is reached prematurely. If the receive FIFO overflows because
the master cannot process packet data fast enough, an RxERR will also be generated.

TDAT042G5 can be placed in loopback on a channel-by-channel basis. When the TDAT042G5 is placed in far-end
loopback (FELB), data from the DE is sent to and processed by the UTOPIA interface. Instead of sending it to the
UTOPIA master, however, the data is sent to the corresponding egress channel and back to the line interface.
When the TDAT042G5 is placed in near-end loopback (NELB), data from the egress channel is transferred to the
corresponding ingress channel, instead of the DE. This data is then processed by the ingress channel and is
returned to the UTOPIA master.
UTOPIA Modes
Each UTOPIA interface mode is capable of supporting various types of traffic with different bandwidth capabilities
as summarized in Table 24. In a point-to-point operational mode, any interface can be configured independently in
any of the defined modes (e.g., channel A passes ATM cells using STS-12c, channel B passes packets, etc.).
It should be noted that the U3 or U3+ (32-bit mode) can only be supported by overloading channel A and B inter-
face pins. Only the control signals from channel A are used. The channel B size and data bits are combined with
the channel A size and data bits to form the 2-bit size and the 32-bit data words. When 32-bit mode is selected,
channels B, C, and D must be configured to be idle (so that channel B will be under the control of channel A in
32-bit mode).
Multichannel multi-PHY (MPHY) capabilities are only supported on interface A by grouping the internal FIFOs and
data paths of channels B, C, and D as needed. This operational mode is described in a later section.

UTOPIA ATM Cell Processing
The UTOPIA block will process ATM packets of 52, 53, 54, or 56 bytes. The standard 53-byte ATM cell structure is
shown in Table 25.
Table 25. Standard 53-byte ATM Cell Structure
In the receive path, TDAT042G5 automatically calculates the HEC (byte 5) and overwrites this byte of the ATM cell.
It is therefore possible to transfer only 52-byte packets through the UTOPIA I/O to increase interface efficiency.
This mode will be referred to as the 52-byte mode. The 52-byte or 53-byte ATM mode is provisioned through
ATM_SIZE_Rx[A--D] (bit 4 of registers 0x020F, 0x0213, 0x0217, and 0x021B) and ATM_SIZE_Tx[A--D]
(
bit 4 of
registers 0x0210, 0x0214, 0x0218, and 0x021C).
U2 Modes. For U2 and U2+, both the 52-byte and 53-byte, 16-bit UTOPIA interface modes are supported for ATM
cells as shown in Table 26.

UT Clocking
TDAT042G5 is compliant with the U2 standard
1
and several versions of the proposed U3 specification
2--6
as a UT
slave device. The U2 standard and proposed U3 specifications define the slave device transmit path (egress) clock
as an input clock. For the U2 case, the slave transmit path clock is generated by the UT master device. For the cur-
rent version of the U3 specification
6
, the transmit path clock for both slave and master devices is generated by the
same external clock source
7
. The U2 standard and current U3 proposed specification
6
define the slave device
receive path (ingress) clock as an input clock. In the U2 case, the slave device receive path (ingress) clock is gen-
erated by the UT master device. In the U3 case, the receive clock for both the master and slave devices is gener-
ated by same external clock source. Previous proposed versions of the U3 specification provided for the case
where the receive path clock could be generated by the slave device. TDAT042G5 can be provisioned in the con-
figuration where it sources the receive path (ingress) clock.
The timing specification for the UT clock is given in the UTOPIA Interface Timing section, pages 268--270.
UT Transmit Path (Egress) Clock
In all UTOPIA modes, the transmit path clock must be provided to TxCLK[D:A] pins as described in Table 5, page
page 31.
UT Receive Path (Ingress) Clock
The receive path clock RxCLK[D:A] pins can be provisioned to be either clock inputs or outputs as described in
Table 5, page 38. Provisioning as either an input or output is done on a per-channel basis through registers
0x020F, 0x0213, 0x0217, and 0x021B (CLOCK_MODE_Rx). In the U2 mode, RxCLK is always provisioned to be
an input. To meet the latest proposed U3 specification, RxCLK is provisioned as an input. To meet special UT
requirements, RxCLK may be provisioned to be a clock output signal. When provisioned as a clock output, the
RxCLK[D:A] is derived from the corresponding TxCLK[D:A] input.
For RxCLK rates greater than 52 MHz, RxCLK must be provisioned to be an output.

UTOPIA (UT) Interface Block
(continued)
UT Receive Input Path (Ingress)
The UTOPIA Rx interface is designed to accommodate ATM cells as well as packet traffic. While the standard
UTOPIA interface transmits and receives ATM cells, this interface has been enhanced to carry non-ATM traffic.
The interfaces supported include the following: UTOPIA Level 2 (U2), enhanced UTOPIA Level 2 (U2+), UTOPIA
Level 3 (U3) in 8-bit mode or 32-bit mode, and enhanced UTOPIA Level 3 (U3+) in 8-bit mode or 32-bit mode.
In the receive direction, data arrives and is sent to one of four channels (A through D). Each channel buffers data
independently and, when sufficient data has been stored in its FIFO, sends the data out of the channel via its UTO-
PIA interface. There are four paths inside the UT core, corresponding to one path per channel. These paths are
labeled A to D. When using 32-bit modes, only the control signals of interface A and size signals of interfaces A
and B are used.
Note: 32-bit mode is supported using channels A and B only. When 32-bit mode is selected, channels B, C, and D
must be configured to be idle (channel B will be under the control of channel A in 32-bit mode).
In normal mode, data arrives into the ingress channel, and control and data information are written into the FIFO.
The data is extracted from the FIFO, and word-aligned on the first byte of data. After word alignment, the data is
sent out of the device via the UTOPIA interface.
Note: The start of packets must be word-aligned, and there can only be one packet per word (required by the defi-
nition of the UTOPIA interface).
FIFO. The 256-byte UTOPIA Rx FIFO is responsible for buffering data from the DE block to be sent to the UTOPIA
interface. The FIFO accommodates four ATM cells or 256 bytes of packet data. In STS-48/STM-16, only one
256-byte FIFO is used. The FIFO is required to manage the asynchronous nature of the UTOPIA interface. Over-
flow will only occur if the master device connected to the UTOPIA interface is having congestion problems. When
overflow occurs and head of line discard is performed, it is possible that part of one packet may be appended to
another (if, for example, an end of packet is discarded along with the data at the head of the FIFO). Because this is
not a desirable operation, it is necessary to discard until the start of the next packet is observed. Data is read from
the FIFO when there is sufficient data in the FIFO. Upon overflow, the RxERR and RxEOP signals are asserted to
indicate to the master the corruption of the current packet.
Sufficient data is defined to be a minimum amount of data in the FIFO (a programmable threshold, low watermark),
or at least one end of packet stored in the FIFO. If the FIFO overflows, the block is responsible for discarding data
until the next start of packet. When this occurs, an alarm is raised. Underflow in the receive direction can occur
when there is no data, or if only part of a packet has arrived and has been transmitted, and is normal behavior.

Receive Cell/Packet Available (RxPA). This signal indicates when the TDAT042G5 receive FIFO can send data
to the master device. The RxPA[D:A] signal behavior depends on the provisioned low watermark in the UTOPIA
interface.
I
One-Cycle Delay Mode. This mode follows the UTOPIA Level 2 Standard. The RxPA response occurs one cycle
after the address is polled. RxENB is asserted to activate the selected PHY. RxDATA and RxSOP are output one
cycle after RxENB is sampled active by the PHY device.
I
Two-Cycle Delay Mode. This mode follows the UTOPIA Level 3 baselined text*. The RxPA response occurs two
cycles after the address is polled. RxENB is asserted to activate the selected PHY. RxDATA and RxSOP are out-
put two cycles after RxENB is sampled active by the PHY device.
I
RxPA[D:A] Assertion. RxPA[D:A] goes high (is asserted) when the amount of data in the receive FIFO has
reached or exceeded the low watermark or there is end of packet (EOP) resident in the FIFO.
I
RxPA[D:A] Deassertion. In ATM mode, the RxPA[D:A] signal goes low (is deasserted) when the FIFO has less
than the low threshold amount of data and there is no EOP inside the FIFO (i.e., part of an ATM cell). Once the
last byte of the current cell is transmitted, and if the amount of data within the FIFO is still less than the low
threshold, RxPA[D:A] is deasserted.
In packet mode, the RxPA[D:A] signal goes low (is deasserted) when the FIFO has less than the low threshold
amount of data and there is no EOP inside the FIFO.
Once the data transfer begins (since the amount of data has reached or exceeded the low watermark), and if
there is no EOP below the low threshold (i.e., a long packet), the RxPA signal is deasserted when the FIFO is
drained by the UTOPIA master device. In this case, the master must closely monitor the RxPA[D:A] signals and
use these signals as data valid indicators to ensure that bad data is not read from the TDAT042G5. TDAT042G5
will deassert the RxPA[D:A] signal immediately when the FIFO is drained.
I
Data Transfer. A TDAT042G5 ingress channel sends data when it has asserted RxPA[D:A] and the master
device requests data (via RxENB[D:A]). In ATM mode, if the master device requests data using RxENB[D:A] and
if the TDAT042G5 has less than the low watermark amount of data to send and there is no end of cell in the FIFO
(RxPA[D:A] is deasserted), then the TDAT042G5 UTOPIA interface will send out data that should be ignored by
the master, i.e., it does not send data from its internal FIFO.
In ATM mode, once an ATM cell transfer starts, the Tx or Rx side must complete the transfer. If the transfer is not
completed, then the cell will be corrupted. The transfer continues until either (1) the end of cell is reached, when
the end of cell exists below the low watermark, or (2) the end of the FIFO is reached. If the end of the FIFO is
reached, no underflow is flagged on the receive side. In ATM mode, the low watermark should be set so that at
least one entire cell is in the FIFO prior to asserting RxPA[D:A].
In packet mode, once the data transfer begins, the RxPA[D:A] signal will remain asserted until the FIFO is
drained if there is no EOP below the low watermark. During the time RxPA[D:A] is asserted, valid data is being
transferred.
RxPA[D:A] is updated on the rising edge of RxCLK[D:A].
In 32-bit mode, only the RxPA[A] pin of port A is used to indicate the packet/cell available status.
I
MPHY Support. When the RxPA signals are used for MPHY direct status, the corresponding
RxCLK[B, C, and/or D] must be provided. This clock will be the same as RxCLK[A].

Figure 23 illustrates the receive-side interface handshaking when operating in point-to-point mode with the RxPA
response provisioned to be a single cycle. In two-cycle mode, the RxSOP, RxDATA, and RxPA signals are
delayed an additional cycle. In the figure, the master device initiates the transfer after observing an asserted
packet available for the channel. The TDAT042G5 samples RxENB low on the first cycle and then asserts
RxSOP/C and RxDATA on the second cycle. RxDATA is sampled on the rising edge of the second cycle by the
master device. Figure 24 illustrates receive-side interface handshaking when operating in two-cycle mode. When
operating in U3+ mode, two-cycle mode must be used.
In this example, the master stops transfer in the middle of the packet. Data with value c is valid on the cycle that
RxENB goes inactive, and when RxENB returns, data is again valid on the first cycle after the slave observes an
active RxENB (data value d).
The packet transfer is complete when the slave asserts the RxEOP signal. If an error occurs in the packet, then the
RxERR signal is asserted simultaneously with the RxEOP. RxERR is ignored if it is not asserted when RxEOP is
active.

UT Transmit Input Path (Egress)
In the transmit direction, data arrives from the various UTOPIA interfaces, and is stored in a 256-byte FIFO, one
per channel. After sufficient data has been stored into the FIFO, it is made available to be sent to the DE.
Like the UTOPIA Rx interface, the UTOPIA Tx interface is designed to accommodate ATM cells as well as packet
traffic. While the traditional UTOPIA interface only transfers ATM cells, this interface has been enhanced to carry
packet traffic. The interfaces supported include the following: UTOPIA Level 2 (U2), enhanced UTOPIA Level 2
(U2+), UTOPIA Level 3 (U3) in 4 x 8-bit mode or 32-bit mode, and enhanced UTOPIA Level 3 (U3+) in 4 x 8-bit
mode or 32-bit mode.
The UTOPIA Tx side can indicate to the ATM side to suspend the transfer, by deasserting TxPA, when necessary.
When the amount of data in the FIFO exceeds its programmable high watermark, it deasserts TxPA. This signal
causes the deassertion of TxPA on the next clock. At this point, the ATM side knows that the UTOPIA Tx block can
only accept a limited number of words, after which it will overflow. In this case, the ATM device must not exceed
writing this limited number of words before suspending the transfer. Transfer is resumed once again when the
FIFO falls below the high watermark. When transferring ATM cells, TxPA must be deasserted four clocks before
the end of cell, or else it must be prepared to accept an entire new cell. When transferring ATM cells, deasserting
TxPA does not immediately suspend the transfer of the current cell because the entire cell can be transmitted with-
out interruption.
Transmit Cell/Packet Available (TxPA). This signal indicates when the TDAT042G5 transmit FIFO can accept
data from the master device. If the FIFO is empty or more than the provisioned space is available in the FIFO,
TxPA[D:A] is set active.
I
One-Cycle Delay Mode. This mode follows the UTOPIA Level 2 Standard. The TxPA response occurs one cycle
after the address is polled.
I
Two-Cycle Delay Mode. This mode follows the UTOPIA Level 3 baselined text*. The TxPA response occurs two
cycles after the address is polled.
I
TxPA[D:A] Assertion. The TxPA[D:A] signal behavior relies on the UTOPIA provisionable watermarks. In
packet mode, TxPA[D:A] goes high when the amount of data in the FIFO is less than the high watermark setting.
In ATM mode, TxPA[D:A] goes high when the FIFO has space to receive a complete ATM cell from the master.
(This requires the high threshold to be set appropriately by the user, i.e., set so that an entire cell can be
received once TxPA[D:A] goes active.)
I
TxPA[D:A] Deassertion. In packet mode, TxPA[D:A] goes low when the amount of data in the FIFO reaches or
exceeds the high watermark. In ATM mode, TxPA[D:A] goes low when there is not enough space in the FIFO to
receive an entire ATM cell. (This requires the threshold values to be provisioned properly, i.e., set low enough
such that when the high watermark is reached, the transmission of the current cell can be completed without
overflowing the FIFO). In ATM mode, TxPA[D:A] will be deasserted four cycles before the end of the current cell
transfer if the FIFO cannot accept a complete ATM cell on the following transmission.
TxPA[D:A] is updated on the rising edge of TxCLK[D:A].
In 32-bit mode, only the TxPA[A] pin of port A is used to indicate the packet/cell available status.
I
MPHY Support. When the TxPA signals are used for multi-PHY (MPHY) direct status, the corresponding
TxCLK[B, C, and/or D] must be provided. This clock will be the same as TxCLK[A].

FIFO. The UTOPIA Tx FIFO is used to create an elastic store that can buffer bursts of data received via the UTO-
PIA Tx, faster than can be transmitted out of the path. After the FIFO exceeds a programmable watermark, it indi-
cates to the UTOPIA Tx master to stop sending data. The master can choose to ignore this request causing the
risk of an overflow. The FIFO block buffers 256 bytes of cell/packet data. The FIFO accommodates four ATM cells
or 256 bytes of packet data. The FIFO is required to manage the asynchronous nature of the UTOPIA interface.
Optionally, in the case of FIFO underflow, a 0x7D207D207D20 . . . will be inserted by the data engine into the mid-
dle of the packet if dry mode is provisioned and the default dry escape sequence is used (0x7D20, where the last
two bytes (the 20 bytes of the default value of 0x7D20) are provisionable). This will be removed at the far end by
the device (provided the link is comprised of two devices and both sides of the link support dry mode).
I
FIFO Watermark Threshold. When carrying ATM cell traffic, this threshold, while measured in words, should be
set at least one cell's length from end of FIFO. The UTOPIA Tx interface, by definition, must be able to accept an
entire ATM cell after the current ATM cell, unless TxPA is deasserted at least four clock cycles before the end of
the current cell transfer.
When carrying packet traffic, however, the threshold can be set higher, as the UTOPIA Tx interface only needs
to accept a limited number of words after deasserting TxPA. The number of words is a programmable value for
the sender, and should be assumed to be at least 2 words for the purposes of setting the threshold.
FIFO high watermark threshold, EGRESS_WATERMARK_HIGH_[A--D][6:0] (addresses 0x0212, 0x0216,
0x021A, 0x021E), should be set as follows.
Table 29. Egress High Watermark Thresholds
Note: The high watermark threshold should be set less than the values in the above table assuming there is no
delay between TxPA deassertion and TxENB deassertion. Then the threshold values may be changed to
optimize UT egress performance and to avoid FIFO overflow.

Figure 25 illustrates the transmit-side interface handshaking when operating in point-to-point mode with the TxPA
response provisioned to be a single cycle. In two-cycle mode, the TxPA signal is delayed an additional cycle. In the
figure, the master device initiates the transfer after observing an asserted packet available for the channel by
asserting the TxENB signal. The master places data and start of packet on the bus the same cycle as TxENB, and
the TDAT042G5 samples the TxSOP and TxDATA on the following clock cycle (rising edge).
In this example, the master stops transfer in the middle of the packet. Data with value c is valid on the cycle that
TxENB goes inactive, and when TxENB returns, data is again valid on the first cycle (data value d).
The packet transfer is complete when the master asserts the TxEOP signal. If an error occurs in the packet, then
the TxERR signal is asserted simultaneously with the TxEOP. TxERR is ignored if it is not asserted when TxEOP
is active.

Multi-PHY Support
In addition to point-to-point UTOPIA mode, the TDAT042G5, as the slave device, can also be configured to support
the polled multi-PHY mode. To operate in multi-PHY mode, channel A must be configured in the polling mode,
since the control signals of channel A are used for all channels. Any combination of B, C, or D can be included in
the polling group, in which case they provide control information to channel A. Channels B, C, and D also can be
configured in any of the UTOPIA modes. In this case, the output is transferred through the channel A interface
(channel A and B interfaces for 32-bit mode). Channels not configured for polling can be operated as point-to-point
connections. If channel A is in 32-bit polling mode, channel B cannot be in point-to- point mode since its interface is
controlled by channel A, while channels C and D may be provisioned as point-to-point connections.
Figure 26 shows a multi-PHY mode when all four channels of the UT are in polling mode.
5-7349(F)r.2
Figure 26. Multi-PHY Configuration of All Four Channels
Mixed mode polling is also possible. For example, for those channels operated in polling mode, it is legitimate for
some of the channels to be in packet mode while others are in ATM mode. However, if one or more of the channels
are in packet mode, channel A should be configured as packet mode to activate control signals for packet transfer.
Multi-PHY operation can be configured by asserting the polling mode enable bit and Tx/Rx address in the respec-
tive port provisioning registers (see port provisioning registers, pages 158--161). Microprocessor provisionable
registers in each channel include a polling mode enable bit and 5-bit Rx address or 5-bit Tx address. The value for
the Tx and Rx address of an MPHY channel must be identical. Both the Rx and Tx directions have a 5-pin address
input to poll and select the appropriate PHY.

UTOPIA (UT) Interface Block

Multi-PHY Support (continued)
In 8-bit or 16-bit multi-PHY mode, only the data bus and the control signals (except the RxPA or TxPA signal) of
channel A are active for the polled group. RxPA[A] indicates the packet/cell availability of the selected or polled
channel. Similarly, TxPA[A] indicates transmit FIFO availability for a selected or polled channel. The remaining
RxPA/TxPA signals for the polled channels are activated and indicate instantaneous or direct status of the particu-
lar channel. In 32-bit multi-PHY mode, the data bus and size control signals of channel B are also active.
TDAT042G5 does not provide a selected packet available (SPA) signal to monitor the status of the current channel
sending/receiving data to or from the master. To prevent the FIFOs from running dry or overflowing in the middle of
a packet transfer, the user must design the UT TDAT042G5 slave-to-master interface with direct status mode
rather than address polling. The direct status of each channel is provided on the associated SPA pin for that chan-
nel. In this mode, the user must guarantee that when channels are switched to receive data from a channel other
than channel A, they immediately reapply the address of channel A to the address bus after the new channel is
selected. The user then gets the direct status SPA signal from channel A. Channels B, C, and D are always directly
sent out of the TDAT042G5. In either receive or transmit, when direct status is used in addition to the direct status
pin for a given interface, its corresponding interface clock pin must be driven by the clock of the A interface.
During the cycle when the selected channel is being changed, the address of the new channel is placed on the
address bus. The user must ignore the RxPA response of the initial channel during the expected response time
(one or two cycles later, depending on the PA response bit when the address of the newly selected channel was
applied).
Figure 27 illustrates the transmit interface timing for the case when the direct status of packet available of channels
A, B, C, and D is present. In this example, channels A and C indicate they can receive data. When the SPA signal
for C is observed, a channel switch is performed by the master by deasserting TxENB and placing the address of
channel C on the address bus. On the following cycle, data is placed on the bus along with the start of packet. In
this example, the TxPA response is configured for two cycles so that the PA response of address 02 results in the
PA of channel C to appear on channel A's output two clock cycles later. Subsequent data sent to the slave will go
to channel C (i.e., data values I, J, etc.).
When the RxPA signals are used for multi-PHY (MPHY) direct status, the corresponding RxCLK[B, C, and/or D]
must be provided. They may be provided via an external UT master, or they may be sourced from the correspond-
ing TxCLK[D:A] pin by using the UT clock source mode (see UT Clocking, page 88).

Multi-PHY Support (continued)
The ATM side sends one RxENB (TxENB) signal to channel A for the grouped channels to select a channel which
has ATM cells/packets (or room) available. An MPHY channel is selected using the following procedures.
1.The ATM layer polls the RxPA[D:A] (TxPA[D:A]) status of a channel by placing its address on the RxADDR[4:0]
(TxADDR[4:0]) lines.
2.In the following cycle, the MPHY channel gives its status by driving RxPA[D:A] (TxPA[D:A]) of channel A.
3.The ATM side selects the MPHY channel by placing the desired MPHY address on the address bus
RxADDR[4:0] (TxADDR[4:0]) during this cycle; RxENB[D:A] (TxENB[D:A]) is deasserted.
4.During the next cycle, the ATM side asserts RxENB[D:A] (TxENB[D:A]), and the selection of an MPHY channel is
made.
Only one MPHY channel at a time is selected for a cell/packet transfer when ATM drives RxENB (TxENB) for
channel A from high to low. However, another MPHY channel can be polled for its RxPA (TxPA) status while the
selected channel transfers data.
Figure 28 shows an example of the single-cycle RxPA response of each channel. In this figure, channels A, B, C,
and D have Rx addresses 00, 01, 02, and 03, respectively. RxPA[A] shows the packet availability of all four chan-
nels. Channels A and C have available packets to send, and channels B and D do not have packets to send. By
driving RxENB[A] low at clock edge 1, the ATM side selects channel A, and packet transfer is started at
clock edge 2. The master samples this data at clock edge 3. At clock edge 4, RxPA[C] shows that channel C also
has a packet to send, and this is reflected to RxPA[A] at clock edge 5. RxPA[B] and RxPA[D] show the direct status
of channels B and D, indicating that they do not have packets to send.

JTAG (Boundary-Scan) Test Block
The JTAG test block provides an IEEE 1149.1 JTAG controller interface for memory BIST, boundary scan, and
32-bit ID register instructions. Details about JTAG (boundary-scan) functionality and interface timing specifications
can be found in MN98-060ASIC-02, HL250C 3.3 Volt 0.25
m CMOS Standard-Cell Library Manual, page 8-1
through page 8-31.
The instruction register length is 3 bits.
Reset of JTAG Logic
There are two events that will reset the JTAG logic:
I
Pulse or pull the TRST pin signal low with no TCK pin signal present. TRST is pulled high on-chip.
I
The TMS pin signal is driven high for five cycles of TCK. TMS is pulled high on-chip.
TRST can be held high during normal device operation only if TRST is pulled low upon powerup.
Line Interface
LVPECL I/O Termination and Load Specifications
The LVPECL buffers are compatible with the temperature independent ECL 100K levels, but the output levels that
are guaranteed are relaxed 30 mV from the actual 100K levels allowing for noise and variations in the power sup-
ply and process.
All LVPECL output buffers require a terminating resistor. These terminating resistors, which must also be con-
nected to both LVPECLREFHI and LVPECLREFLO, go to a common terminating voltage. All of the terminating
resistors used with a chip must be identical precision (1%) resistors. The value of these terminating resistors is
usually chosen to match the characteristic impedance of the board. To save on power, a terminating voltage equal
to V
DDD
2 V is available in most ECL systems. The minimum value of the terminating resistor that can be used on
these bufers is 50
. This is also the standard termination used in most ECL systems. Larger values of resistance
will save power, but will also slow down the high-to-low transition of the output, since it is RC limited.
if no V
DDD
2 V supply is available, a larger value resistor may be connected directly to GND. It should be chosen
such that the current through it does not exceed the current through a 50
resistor to V
DDD
2 V (21 mA in the
high state). This large resistor will most likely be a poor match to the board impedance. The match can be
improved by the user of a Thevenin equivalent resistor pair. Such a Thevenin equivalent resistor will burn much
more system power (but not on-chip power) than would a single resistor, but it does allow for impedance matching
in the absence of aV
DDD
2 V supply. Termination resistor options are shown in Table 30.
Experienced ECL designers sometimes use the (bipolar) ECL output buffers in a tied-OR configuration. Unfortu-
nately, this cannot be done with these LVPECL buffers.
Table 30. Nominal dc Power for Suggested Terminations
Note: The value is the average of the high and low states in LVPECL output buffer and external terminating resis-
tors, for a single-ended output. The values double for double-ended outputs.

LVPECL I/O Termination and Load Specifications
(continued)
The input common mode range for LVPECL differential buffers is from 1 V to 2.75 V; and the swing needs to be at
least 300 mV. So basically what it means is the lowest voltage on the input should be no lower than (1 V 0.150 V)
and the highest voltage on the input shouldn't be more than (2.75 V + 0.150 V). So if the differential swing is
800 mV, then the common mode range would be 2.5 V down to 1.25 V. This is all for 3 V buffers.
Interface Description
Microprocessor Interface
This device is equipped with a generic 16-bit microprocessor interface that allows operation with most commer-
cially available microprocessors. Input MPMODE is used to configure this interface into one of two possible modes
(synchronous or asynchronous). In synchronous mode, the microprocessor interface can operate at speeds from
1 MHz up to 66 MHz.* In asynchronous mode, the internal 78 MHz system clock is used to operate this interface.
Table 31. MPU Modes
The host interface is designed to connect directly to a commonly used asynchronous or synchronous host bus.
The interface to this block includes a separate clock, MPCLK, which is used in the synchronous interface mode.
The interface is only a slave on the host bus. There is no posting of writes in the host interface; all registers are
directly accessible. The microprocessor interface pins use 3.3 V (5 V, TTL-tolerant) CMOS I/O levels. The micro-
processor interface timing specifications are given in the Interface Timing Specifications section (see Table 163--
Table 166, pages 257--263).
* All status counters must be read within the 1-second time window of the PMRST. If this is not the case, counter values will be l ost.

General-Purpose I/O Bus (GPIO)
GPIO[3:0] are bidirectional pins. They can be configured individually as input or output by writing to the GPIO mode
and GPIO output configuration registers (addresses 0x0013, 0x0014, 0015; see register descriptions, page 152).
The value to be output is written into the GPIO output register (address 0x000F; see register descriptions,
page 150). To use the GPIO pins as outputs, set the GPIO output configuration bits (bits 8 and 0) to 1, and set the
GPIO mode bits GPIO[3:0]_DIRECTION_ I/O (address 0x0013, bits [3:0]) to 1.
The input value is read from the GPIO input register (address 0x000A; see register description, page148). GPIO
pins can also be used to generate an interrupt upon a change in value. An interrupt can be generated on either the
input level or edge, depending on the GPIO mode register. Figure 29 shows how the GPIO functions.
5-7058(F)r.6
Figure 29. GPIO Functionality
If a GPIO pin is an input, the logic value on the pin can be read from a software register. The GPIO pin can also be
programmed to generate a level-sensitive interrupt or a positive edge-triggered interrupt contributing to the external
interrupt pin.
If a GPIO pin is an output, the value provisioned will appear on the device pin immediately.

Reset
If the reset pin RST (C7) is forced low, the software registers will be placed in their default powerup state. The
device will lose its previous state, and data path continuity will be lost. An internal 100 k
pull-up and a Schmitt-
trigger input is provided for this pin. Reset can be generated from software by writing 0x0005 to the core resets reg-
ister (0x000E; see register description on page 149 and timing on page 263).
Performance Monitor Reset (PMRST)
A 1 Hz clock (PMRST) is provided to all internal macrocells. This clock is used to control the 1-second binning of
coding violations (CVs) and alarms. The source of this clock is selectable from one of the three following sources:
I
The PMRST pin (D7)
I
A software controllable register (0x000E; see register description on page 149)
I
An internal 1-second counter (sourced from the 77.76 MHz transmit clock).
This is configured by the line provisioning register (address 0x0010). When under software control, writing 0x0080
to core resets register (address 0x000E) will generate a PMRSTX pulse.

Performance Monitor Reset (PMRST)
(continued)
Address 0x0010, bits 8 and 9 of the core register set defines the mode of operation for PMRST. Address 0x000E,
bit 7 provides the software-controllable reset function (see Register Maps section, page 112). When this bit is set
to 1, the PMRST signal goes high. The register will automatically be reset to 0, and the PMRST signal will go low
after 500 ms.

Description
00
PMRST comes from external pin (1 Hz, 50% duty cycle signal).
01
PMRST comes from internal 1-second counter (1 Hz, 50% duty cycle signal).
Writing a logic 1 to the PMRST bit (core register 0x000E, bit 7) in this mode will
reset the counter so that a 0
1 transition occurs on the PMRST within 10 clock
cycles of the 77.76 MHz clock.
11
PMRST is software controlled. Writing a logic 1 to the PMRST bit (core register
0x000E, bit 7) will cause a 0
1 transition on the internal PMRST signal. This
pulse will be high for 100 cycles of the 77.76 MHz clock and low for 100 cycles of
the 77.76 MHz clock. Writing the PMRST bit to a logic 1 during this 200 clock
cycle interval will have no effect (2.57
s). The PMRST rising edge must occur
within 10 clock cycles of writing the PMRST bit.

Loopback Operation
Figure 32 illustrates the different types of loopback provided in the device. Loopback is controlled by core register
0x0012, loopback control (see register description on page 151).
5-7061(F)r.4
Figure 32. Loopback Operation
In the following description, only the data path from Terminal A to B is discussed, but the same terms apply to the
reverse direction.
Near-End Loopback
The packet/cell payload is looped back to the data source (Layer 2 device) as soon as it crosses the Layer 1 to
Layer 2 boundary (UTOPIA block).
Far-End Loopback
The packet/cell payload is looped back to the facility (optical) data source as soon as it enters the UTOPIA block of
Terminal B. The data does not enter the Layer 2 device. The total delay from receive data input to transmit data
output in far-end loopback (FELB) mode is approximately 2
s.
Terminal Loopback
The SONET/SDH signal is looped back at the terminal (line interface) block, and is returned to the Layer 2 device.
For terminal loopback of UTOPIA ports B, C, or D to function, UTOPIA port A must be provisioned for terminal loop-
back. This is because only the Tx clock from port A is used in terminal loopback mode.
Facility Loopback
The facility (optical) data signal is looped back to the facility as soon as it enters the Terminal B line interface block.
SONET facility loopback is only available in STS-3/STM-1 and STS-12/STM-4 modes.

Register Access Description
Register address space is defined by the 16-bit address word of ADDR[15:0] (see Table 6, page 41). Bits 15
through 13 must be 0. Bits 12 through 9 map to the major functional blocks as shown in Table 35. The usable
address space is also shown in Table 35.
Register addresses outside of the space defined in Table 35 must not be addressed, i.e., written or read.
Table 36--Table 40 are the register maps. Details of the register functions are given in the following register
description tables. Note that the usable register address space is not contiguous. Register addresses not specifi-
cally identified in the following tables are reserved and must not be addressed, i.e., written or read. Registers and
bits that are reserved must not be written or must be written to the indicated default value. In Table 36--Table 40,
the registers may be read only (RO), read/write (R/W), write only (WO), or clear-on-read or clear-on-write
(COR/W).
The core registers must be written prior to provisioning any other registers (1) to establish the internal clock rates
for the device, and (2) because writing to certain core registers resets the remainder of the device. Certain clocks
must be present to read/write registers prior to provisioning the device.
One of the following clocks must be present prior to provisioning to enable register access.
I
TxCKP and TxCKN
I
MPU clock (microprocessor interface synchronous mode only)
Provisioning must be implemented in the following sequence.
I
Core register 0x0010 (mode) must be provisioned first
I
Core register 0x0011 (channel [A--D] control) second
I
Remainder of the core registers must then be provisioned (order does not matter)
It is recommended, but not required, that the remainder of the device be provisioned in the following order.
I
OHP, PT, and DE blocks (order does not matter)
I
UT block to turn on the data source to the master and slave

OHP Registers
This section gives a brief description of each register bit and its functionality. All algorithms are described in the
main text of the document. The abbreviations after each register indicate if the register is read only (RO), read/

J0MONMODE[A--D][1:0]
J0 Monitoring Mode. The four modes are,
00 = The OHP will latch the value of the J0 byte
every frame for a total of 16 bytes. The OHP will
compare the incoming J0 byte with the next
expected value (the expected value is obtained
by cycling through the previously stored 16
received bytes in round-robin fashion) and set
the event bit if different.
01 = This is the SONET framing mode. The
hardware looks for 0x0D followed by 0x0A to
indicate that the next byte is the first byte of the
path trace message. The J0 byte is continu-
ously written into J0DMON with the first byte
residing at the first address. If any received byte
does not match the previously received byte for
its location, then the event bit is set.
10 = This is the SDH framing mode. The hard-
ware looks for the byte with the MSB set to 1,
which indicates that the next byte is the second
byte of the message. The rest of the operation
is the same as the SONET framing mode.
11 = A new J0 byte J0DMON[0][7:0] will be
detected after CNTDJ0Z0[3:0] consecutive con-
sistent occurrences of a new pattern in the J0
overhead byte. Any changes to this byte are
reported to J0MISE and J0MISM. These event

Table 86 and Table 87 show values of Ns, L, M, and B for STS-3/STM-1, STS-12/STM-4, and STS-48/STM-16 to
set and clear the BER indicator. SF registers are 0x0452--0x0469, and SD registers are 0x043A--0x0451.
All SF/SD set and clear values are hexadecimal.
Table 86. Ns, L, M, and B Values to Set the BER Indicator
* These are the numbers to be provisioned in TDAT042G5. The actual values of the BER algorithm are 1 greater than the actual values shown.
These BER values cannot be provisioned because the maximum value of L is 0xF (i.e., L is a 4-bit register).

PT Registers
This section gives a brief description of each register bit and its functionality. All algorithms are described in the
main text of the document. The abbreviations after each register indicate if the register is read only (RO), read/write
(R/W), write only (WO), or clear-on-read or clear-on-write (COR/W).
0x indicates a hexadecimal value in the Reset Default column. Otherwise, the entry is binary. This is true for every
register table in the document.
Table 95. Register 0x0800: PT Macrocell Version Number (RO)
Reset default of register = 0x0000.

DE Registers
This section gives a brief description of each register bit and its functionality. All algorithms are described in the
main text of the document. The abbreviations after each register indicate if the register is read only (RO), read/write
(R/W), write only (WO), or clear-on-read or clear-on-write (COR/W).
0x indicates a hexadecimal value in the Reset Default column. Otherwise, the entry is binary. This is true for every
register table in the document.

Reset default of register = 0x0001.
Table 112. Register 0x1001, 0x1002: DE Interrupts (0x1001 is RO, 0x1002 is RO and COR/W)
Reset default of registers = 0x0000.
Note: Register 0x1001 is cleared by accessing the source register of the interrupt. The source register must be

SDL SDLMSI register (0x1606, bit 0) is read.
These interrupts will generate a DE interrupt.

DEINTCH[3:0]
Channel Interrupt. Active-high interrupt bit on a per-
channel basis. These bits are the ORing of all interrupt bits
associated with the error counters described in registers
0x1100--0x111F (pages 238--page 143). The error counter
can be inhibited from contributing to the interrupt by setting the
appropriate mask bit in register
DEDINTM[0--3] (addresses 0x1180, 0x1182, 0x1184, 0x1186
on page 243).
The following interrupts will generate a DE interrupt:
Bit 0 corresponds to channel 0 interrupt.
Bit 1 corresponds to channel 1 interrupt.
Bit 2 corresponds to channel 2 interrupt.
Bit 3 corresponds to channel 3 interrupt.
Note: This bit indicates that the channel is experiencing an
interrupt. This bit will not clear on a read or a write of
this register, but will clear when the counter interrupt
register DEDINTM[0--3] (addresses 0x1181, 0x1183,
0x1185, 0x1187 on page 244) is read or written.

From IETF RFC 1622, invalid sequences are
the following:
1. Frames which are too short (less than 4
data bytes). See register PM_FC2_0
(addresses 0x1108--0x110F).
2. Frames which end with a control escape
octet followed immediately by a coding flag
sequence (0x7D7E).

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.

Handling Precautions
Although protection circuitry has been designed into this device, proper precautions should be taken to avoid expo-
sure to electrostatic discharge (ESD) during handling and mounting. Agere employs a human-body model (HBM)
and a charged-device model (CDM) for ESD-susceptibility testing and protection design evaluation. ESD voltage
thresholds are dependent on the circuit parameters used in the defined model. No industry-wide standard has
been adopted for the CDM. However, a standard HBM (resistance = 1500
, capacitance = 100 pF) is widely used
and, therefore, can be used for comparison purposes:

TDAT042G5 SONET/SDH
Interface Timing Specifications
This section specifies the interface timing requirements for the microprocessor interface, line interface, UTOPIA
interface, and SONET transport overhead (TOAC) interface.
Microprocessor Interface Timing
In all modes of the microprocessor interface, the CS may be held active continuously without affecting the function-
ality of TDAT042G5. There is no minimum time between successive microprocessor accesses to TDAT042G5, i.e.,
successive reads or writes may be back to back.
Synchronous Mode
The synchronous microprocessor interface mode is selected when MPMODE (pin D8) = 1. Interface timing for the
synchronous mode write cycle is given in Figure 38 and in Table 163 (pages 256--257), and for the read cycle in
Figure 39 and in Table 164 (pages 258--259).

Reset
Software Reset. Writing the binary value 101 to SWRST (core register 0x000E, bits 2--0) causes a 0 to 1 transi-
tion on the internal PMRST signal. This pulse will be high for 100 clock cycles and then low for 100 clock cycles of
the 77.76 MHz internal clock. Writing a logic 1 to these bits during this 200 clock-cycle interval (2.57
s) has no
effect.
Interrupt. Occurrence of an interrupt is event driven. The interrupt pin, INT (B7), will be deasserted after a mini-
mum of either one MPU clock cycle in the synchronous microprocessor mode or 13 ns in the asynchronous micro-
processor mode after clearing the interrupt register.
