General Description

The M21130, designed for today's demanding telecom and

datacom applications, is a low-power BiCMOS, high-speed

68 x 68 crosspoint switch with input equalization and built-in

system test features.
The device consumes as low as 8 Watts of power (typical at

2.5 V) with all channels operational. In addition, the PowerSca-
ler

features offer dynamically scalable switch settings to fur-

ther reduce power consumption. Unused portions of the core
can be automatically (SmartPower

) turned off, without affect-

ing the operation of the remaining channels.
To improve signal quality, each input buffer is preceded by an
input equalizer (IE), which removes ISI jitter that is usually
caused by PCB skin effect losses. The IE circuit opens the input
data eye in applications where long PCB traces and cables are
used. The input equalizer can be enabled on a per channel ba-
sis.
The device supports data rates from 0 to 3.2 Gbps on each

channel, allowing any combination of SONET, Fibre Channel

(1x, 2x, 10x), InfiniBand, Gigabit Ethernet and 10 Gbps Ether-

net traffic.
Built-in system test features simplify design, verification, and

production testing of the system. The switch includes an on-
board 2

1 pseudo-random bit sequence transmitter (PRBS

TX) and receiver (PRBS RX).
Three-stage switch fabrics with up to 2,313 x 2,313 ports, car-

rying up to 7.4 Terabits per second of traffic, can be designed

using this non-blocking switch, with multi-cast and broadcast

abilities.
All inputs and outputs are differential PCML (positive current

mode logic) with 2.5 V or 3.3 V supply.

Applications

Large N x N cascaded switch fabrics, up to 7.4 Terabits/
second
DWDM Switches
Fiber-optic Telecom Systems (OC-48/OC-48 FEC)
Telecom & Datacom Switches
Storage Area Network (SAN) Switches (Fibre Channel,
2x Fibre Channel, and 10x Fibre Channel)
10 GbE parallel, GbE, and Infiniband networks
Packet Switching
High-speed Automated Test Equipment

Serial Interface and Switch Programming

Introduction

The crosspoint switch uses +2.5 or 3.3 V CMOS interface levels to program the Switch State (SS). All control inputs have a 50 k

internal pull-up except for xInDis and xOutDis, which have internal pull-downs. The communication protocol may be either a serial
synchronous interface or an 8-bit parallel asynchronous interface. Either interface can:

1. Program the switch state

2. Individually enable/disable inputs/outputs

3. Access control registers and auxiliary functions

4. Read back the current state of the switch

This section details the operation of the I/O interface and switch programming. The auxiliary functions and address mapping are
explained in the section, Switch Function Details.

Register Concept

The various switch functions are controlled by 8-bit registers that are addressed by the 8-bit address (ADDR) bus. The register
contents are transferred via the 8-bit data (DATA) bus during a READ or WRITE.

Switch State Register Concept

The Switch State of the crosspoint switch uses a double buffered register. The Active Configuration Latch (ACL) holds the current
switch setting while the Input Configuration Latch (ICL) holds either the current switch setting or the next switch setting, depending on
the mode of operation.

The xSET Mode register (ADDR=E7h) selects the two modes of operation. DATA=00h enables Mode 1, which is the default mode
after a reset. In Mode 1, the switch state changes with each WRITE to the register that determines the SS. In the WRITE mode, as
xDS goes low, the input channel specified by DATA for the output selected by ADDR passes directly through the double buffer (ICL/
ACL), which routes the selected input to the newly selected output channel. On the rising edge of xDS, ICL and ACL both store (latch)
this SS.

Figure 3

represents a timing diagram for the Parallel I/O, Mode 1.

In Mode 2, the SS is written first to the ICL and the switch state does not change. With either the hardware or software xSET
command, the contents of the ICL transfer to the ACL, changing the SS. This mode allows 1 to 68 channels to change simultaneously.
The hardware xSET mode is enabled by DATA=10b written into xSET Mode (ADDR=E7h). On the falling edge of xSet, the contents of
the ICL pass to the ACL, changing the SS. On the rising edge of xSet, the SS is latched.

Figure 3

illustrates the timing for a parallel

write operation.

Figure 4

illustrates the timing for a parallel read operation.

Table 10

defines the timing specifications for parallel write

operations.

Table 11

defines the timing specifications for parallel read operations.

To enable the software xSet mode, where the xSet command is sent via a software command rather than a hardware command, a
value of 01h should be written into the xSET Mode register (address E7h). Once in the software xSet mode, an xSet command can be
issued with a write of any value to the software xSET register (address E8h). A write of any value to the software xSET register
(address E8h) will update the ACL with the current ICL contents and change the switch state.

Parallel I/O Overview

Setting the hardware pin Ser/xPar low enables the parallel I/O mode. An 8-bit address bus addresses the register and a bi-directional
8-bit data bus can read and write the register contents. The active low data strobe (xDS) latches (stores) the data in the register on
the rising edge of xDS. The double buffer (ICL/ACL) is transparent to the data (mode 1) when xDS=L, so the SS will change on the
falling edge of xDS. On the rising edge of xDS, the switch state will be stored into the register. The active low pin xCS gates the I/O
and the R/xW gates whether a read or write operation is being performed. During a read operation, the current configuration of the
addressed channel is read back from the device if a read is to an output channel register, regardless of the contents of the ICL.

Serial I/O Overview

To configure the M21130 for the serial programming mode, the hardware pin Ser/xPar must be high. A serial I/O operation is initiated
when xCS transitions from a high state to a low state. Data is shifted in on SDI on the falling edge of SCLK, and shifted out on SDO
on the rising edge of SCLK. A 10-bit sequence addresses a register, as illustrated in

Figure 5

. The Start Bit (SB) is first in the bit

sequence, followed by the Operation Bit (OP) and the 8-bit ADDR (MSB first). For a write operation, an 8-bit DATA (MSB first) directly
follows the last address bit. The start bit is 1 in all cases, and the operation bit is 1 for a read and 0 for a write operation.

Figure 5. Serial Word Format

Figure 6

illustrates the serial Write mode timing diagram. To initiate a Write sequence, xCS goes low before the falling edge of SCLK.

On each falling edge of SCLK, the 18-bits consisting of the SB = 1, OP = 0, ADDR, and DATA, are latched into the input shift register.
The rising edge of xCS must occur before the falling edge of SCLK for the last bit. Upon receipt of the last bit, one additional cycle of
SCLK is necessary before the input DATA transfers from the input shift register to the addressed register. If consecutive read/write
cycles are being performed, it is not necessary to insert an extra clock cycle between read/write cycles, however one extra clock cycle
is needed after the last data bit of the final read/write cycle to complete the operation.

Figure 7

illustrates the serial Read mode timing diagram. To initiate a read sequence, xCS goes low before the falling edge of SCLK.

On each falling edge of SCLK, the 10-bits consisting of SB = 1, OP = 1, and the 8-bit ADDR are written to the serial input shift register
of the M21130. On the first rising edge following the address LSB, the SB and 8-bits of the DATA are shifted out on SDO. The first bit
output on SDO for a read operation is always 0.

Figure 7. Serial Read Mode

On a Write cycle, any bits that follow the expected number of bits are ignored, and only the first 16-bits following SB and OP are used.
On a Read cycle, any extra clock cycles will result in the repeat of the data LSB. An invalid SB or OP renders the operation undefined.
The falling edge of xCS always resets the serial operation for a new Read or Write cycle.

Switch Function Details

Introduction

Many functions of the crosspoint switch can be accessed through hardware pins or through software via the serial/parallel interface. In
some cases, both software and hardware can access the same function. This section describes the various functions in detail.
Information on individual registers is listed in

Table 14

and

Table 15

Input Equalization

To reduce jitter caused by inter-symbol-interference (ISI), input equalization (IE) circuitry is integrated into each input channel of the
M21130. ISI is typically generated when the signal is routed through long PCB traces, cables, or backplane connectors. The IE circuit
for each input channel is enabled by default. The IE for each channel can be individually enabled/disabled through the "I/O Individual
Channel Enable" registers, addresses 80C3h. Bit 3 of this register is used to enable or disable the IE. Note that bit 2 of register EBh
must be set to "1" to individually enable/disable the IE for a particular channel.

Switch Setting

The previous section described the details of the programming interface for register writing, reading, and configuring the switch.

Table 14

lists the allowable addresses for the crosspoint switch. The input channel selection registers are mapped to

ADDR=00h...43h. ADDR 00h is assigned to output channel 0, ADDR 01h to output channel 1, and ADDR 43h to output channel 67.
DATA associated with ADDR are 00h...43h and are mapped to the input channel that is routed to the selected output. For example if
ADDR=05h and DATA=02h, then output #5 gets input #2. To Read the current configuration of a particular output channel, the
selected channel is specified by ADDR and the resulting DATA is the input channel # routed to the selected output. The Next Switch
State (NSS) in the ICL cannot be read back if it differs from the ACL. The default state after power on is channel 0 broadcast to all
outputs (all registers cleared). Note that bit D[7] of the register data (regardless of the serial or parallel interface option) is undefined
for a READ and ignored for a WRITE.

Input/Output Enable

The xInDis and xOutDis pins will disable the inputs and outputs, respectively. Setting xInDis=L globally disables all inputs and,
conversely, setting xOutDis=L globally disables all outputs. Hardware disable has priority. If not hardware disabled (xInDis/
xOutDis=H), the I/O enable register (ADDR=EBh) provides control for all off, all on, or individual control. If individual control is
selected, the 68 registers for I/O individual channel enable (ADDR=80h...C3h) determine the input/output buffer status. For the
outputs, a disabled state implies turning off the output stage current source to save power. With built-in pull-up resistors, both positive
and negative outputs will default to the high logic state when disabled.

If an output is enabled, but the input channel routed to the output is disabled, the input stage current source will be off and the input
signal will not drive to the output and the positive and negative outputs will be in an indeterminate state. The default state is the I/O
enable register set to all input/outputs off, and the I/O individual channel enable registers set to all inputs/outputs off.

The I/O enable register (ADDR=EBh) determines the global state of the input/output registers. If D[2]=0, the two LSB determine if the
inputs/outputs are all off (global). If D[2]=1, the two LSB are ignored and the I/O individual channel enables take priority.

xRST/xTEST

The reset function provides a power-on reset and a general reset to default settings for all registers. The xTest pin is used by
Mindspeed Technologies for internal testing and should be tied to V

for normal operation. A hardware reset should be issued to the

M21130 after initial power up. To issue a hardware reset to the M21130, the xRST pin should be pulled low for a minimum of 20 ns and
then pulled to a high state. This will reset all registers to their default settings. Both the ICL and ACL are cleared resulting in the switch
core set to broadcast channel 0 to all channels. PRBS Tx and Rx are disabled and error flags are cleared. A hardware reset should be
sent to the M21130 after power-up.

If xTest=L after reset, then channel 0 is broadcast to all outputs and all inputs/outputs are enabled regardless of the I/O enable and I/
O individual channel enable registers' contents. These features are used for Mindspeed Technologies internal die testing. For normal
operation, xTest=H and xRst =H. Issuing a software reset requires two consecutive Writes to the software reset register (ADDR=EFh)

with DATA=01h. If the next Write is not to the software reset register, the register will clear and two additional consecutive Writes will
be needed. A third write to the software reset register is required to bring the device out of reset and restore all register settings to
their default values. A Hardware reset has priority over a software reset.

Revision Code

A read from register ADDR=F0h (chip revision) results in a readback of the official chip version.

PRBS TX and RX

The PRBS TX section provides a NRZ PRBS pattern or a 22-bit programmable pattern. The data rate of the PRBS Tx output is
determined by the external clock, ClkTxP/ClkTxN (PCML), which is gated by setting the hardware pin external pin xEnTx=L or by
setting the pwr_tx bit of the PRBS power/enable (ADDR=E0h) register. With xEntx=L, output data updates with each rising edge of
ClkTxP. Note that a value of 01h needs to be written into register address E4h to establish the correct seed for the PRBS patterns.
The single-ended output Trig (ClkTxP/16) can be used as a scope trigger to observe the PRBS patterns. The Trig is a PCML output
with a minimum swing of 150 mV. The Trig pin is designed to drive 50

; however, the backmatch is 200 . Data output is via the

differential DoTxP/DoTxN (PCML) pins. The PRBS Rx section takes in a NRZ PRBS pattern and checks for any bit errors. The user
must provide a phase aligned differential clock and data signal for the PRBS receiver, which can be obtained by passing the data
through a clock and data recovery device and connecting the CDR clock and data outputs to the M21130 PRBS Rx inputs. ClkRxP/
ClkRxN clock and DiRxP/DiRxN data are both gated by the external pin xEnRx or the pwr_rx bit of the PRBS power/enable
(ADDR=E0h) register. The falling edge of ClkRxP is expected near the middle of the data eye as illustrated in

Figure 8

. The PRBS

Receiver Program timing parameters are listed in

Table 13

Figure 8. PRBS Receiver Timing

When the PRBS RX detects an error, PError will be high. The first and each subsequent error will increment an internal
8-bit counter (PRBS RX error count register ADDR=E2h). If the errors exceed 256 (counter overflow), the counter will stay at 255 until
a hardware or software reset. To read the RX error counter register requires a WRITE of any value to copy the current contents of the
running error register into the PRBS RX error count register. A subsequent READ yields the error count as of the last WRITE. The RX
reset can be initiated by the xRstRx pin or by the rst_rx bit in the PRBS control (ADDR=E1h) register. Upon reset, the PRBS RX error
counter clears and PError resets.

PRBS RX error count will always contain the current value of the error count register. Dividing the value by the time of the test is a
rough estimate of the bit error rate. If there has been more that 256 errors, the PRBS RX error count register will always read FFh until
cleared.

The PRBS pattern length register (ADDR=E3h) sets the pattern length (n) of a 2

-1 pattern. D1 and D0 (rxlen) set the length of the

PRBS Rx and D2 is the rxcirc bit. If D2=L, then the first `n' bits check the input pattern. If the first 23-bits are error free, then each
additional error is counted once. If D2=H, the recirculation mode is enabled and the last `n' bits check the n+1 bit. If a bit error did
occur, the error bit would shift through the `n' bits of the reference resulting in multiple error counts due to one error. Bits D3 and D4
(txlen) determine the pattern length of the PRBS TX. For both the rxlen and txlen:

Value 00b produces a 2

-1 pattern with the polynomial D7+D6+1.

Value 01b produces a 2

-1 pattern with the polynomial D15+D14+1

Value 10b produces a 2

-1 pattern with the polynomial D23+D18+1

Value 11b produces a repeating 22-bit pattern.

For the 2

-1, the higher bit patterns conform to the specification, Consultative Committee on Industrial Telegraph and Telephony

(CCITT) Rec. 0.151. The lower pattern is commonly used with commercially available bit error rate testers. The 22-bit pattern is a
repeating user-programmed pattern. The error counter will work with all four patterns.

The TX starting pattern used for all four pattern modes can be user programmed with the three PRBS pattern registers, ADDR=E4
through E6h. ADDR=E4h specifies the first 8-bits (Pattern[0 .. 7] of the user pattern, ADDR=E5h specifies the next 8 bits (Pattern[8 ..
15]), and ADDR=E6h specifies the highest seven bits (Pattern[16 .. 22]). An rst_tx and rst_rx (software) needs to be invoked for both
the RX and TX.

To save power, both the PRBS Tx and Rx can be powered off. The PRBS Power/Enable register, ADDR=E0h, controls these
functions.

Core Power Saving

The CoreCtrl register enables the core power-saving modes. Register CoreCtrl[1] = 0 powers down the switch core and the PRBS Tx/
Rx (default power on).

core control (default).

Smartpower reduces power dissipation by as much as 30% by automatically powering down unused circuitry in the switch core once
a switch configuration has been programmed. When the switch configuration is changed, Smartpower will enable/diable the
necessary mux circuitry within the switch core. The actual power savings will vary across different switch configurations. This process
takes approximately 10 ns to complete and will increase the time required to reconfigure the switch core. In applications where the
switch core will be left in the same state for a relatively long period of time this is typically not an issue and is worth the power savings.
In applications where the minimum switch reconfiguration time is needed, such as packet switching applications, Smartpower can be
disabled through software.

Digital Slope Control

Because high speed interface operation requires high speed rise and fall times through the IC, it is possible to generate jitter with the
digital control. To minimize this effect, and realizing not all applications will require the fastest programming times, slope control
internal registers ADDR=EDh and EEh are provided to set the edge rate with respect to the interface I/O speed. The registers and
functions are listed in
