DESCRIPTION
The Infineon (former
SIEMENS
company) single mode ATM
transceiver complies with the ATM Forum's
Network Compati-
ble ATM for Local Network Applications document and ANSI's
Broadband ISDN--Customer Installation Interfaces, Physical
Media Dependent Specification, T1.646-1995, Bellcore - SONET
OC-3 / IR-1 and OC-12 / IR-1, ITU-T G.957 STM-1 / S.1.1 and
STM-4 / S.4.1. ATM was developed to facilitate solutions in mul-
timedia applications and real time transmission. The data rate is
scalable, and the ATM protocol is the basis of the broadband
public networks being standardized in the International Tele-
communications Union (ITU), the former International Telegraph
and Telephone Consultative Committee (CCITT). ATM can also
be used in local private applications.
The Infineon single mode ATM transceiver is a single unit com-
prised of a transmitter, a receiver, and an SC receptacle. This
design frees the customer from many alignment and PC board
layout concerns. The module is designed for low cost WAN
applications. It can be used as the network end device interface
in workstations, servers, and storage devices, and in a broad
range of network devices such as bridges, routers, and intelli-
gent hubs, as well as wide area ATM switches.
This transceiver operates at 622.080 Mbits per second from a
single power supply (+5 Volt or 3.3 Volt). The differential data
inputs and outputs are PECL compatible.
Functional Description
This transceiver is designed to transmit serial data via single
mode cable.
Functional Diagram
The receiver component converts the optical serial data into
PECL compatible electrical data (RD and RDnot). The Signal
Detect (SD, active high) shows whether an optical signal
is present.
The transmitter converts electrical PECL compatible serial data
(TD and TDnot) into optical serial data.
The following versions are available:
1. AC/DC Transceiver
Tx is AC coupled with differential 100
load. Rx has standard
PECL output and is DC coupled.
2. AC/AC TTL Transceiver
Tx and Rx are AC coupled. Tx has differential 100
load. Signal
Detect is TTL compatible.
3. DC/DC Transceiver
Standard PECL inputs and outputs Tx and Rx are DC coupled.
This version contains an Input Signal Monitor (ISM), that
switches off the optical power if a continuously low level is
applied at Data Input.
4. AC/AC PECL Transceiver
Tx and Rx are AC coupled. Tx has differential 100
load. Signal
Detect is PECL compatible.
The transmitter contains a laser driver circuit that drives the
modulation and bias current of the laser diode. The currents are
controlled by a power control circuit to guarantee constant out-
put power of the laser over temperature and aging. The power
control uses the output of the monitor PIN diode (mechanically
built into the laser coupling unit) as a controlling signal, to pre-
vent the laser power from exceeding the operating limits.
Single fault condition is ensured by means of an integrated
automatic shutdown circuit that disables the laser when it
detects transmitter failures. A reset is only possible by turning
the power off, and then on again.
The transceiver contains a supervisory circuit to control the
power supply. This circuit generates an internal reset signal
whenever the supply voltage drops below the reset threshold.
It keeps the reset signal active for at least 15 milliseconds after
the voltage has risen above the reset threshold. During this
time the laser is inactive.

Caution
The use of optical instruments with this product will
increase eye hazard!
Usage Restrictions
The optical ports of the modules should be terminated with an
optical connector or with a dust plug.

APPLICATION NOTE
ATM transceivers and matching circuits are high frequency
components and shall be terminated as recommended in the
application notes for proper EMI performance. Electromagnetic
emission may be caused by these components.
To prevent emissions it is recommended that cutouts for the
fiber connectors be designed as small as possible.
It is recommended that the Tx plug and the Rx plug be
separated with a bar that divides the duplex SC opening.

APPLICATION NOTE
Single Mode 1300 nm 622 MBd ATM 1x9 Transceiver, DC/DC Version
The following Application Notes assume Fiber Optic Transceiv-
ers using 5 V power supply and SerDes Chips using 3.3 V
power supply. It also assumes no self biasing at the receiver
data inputs (RD+/RD-) of the SerDes chip (Refer to the manu-
facturer data sheet for other applications). 3.3 V-Transceivers
can be directly connected to SerDes-Chips using standard
PECL Termination network.
Value of R1...R4 may vary as long as proper 50
termination to
V
EE
or 100
differential is provided. The power supply filtering
is required for good EMI performance. Use short tracks from
the inductor L1/L2 to the module V
CC
Rx/V
CC
Tx. We strongly
recommend a GND plane under the module for getting good
EMI performance.
The transceiver contains an automatic shutdown circuit. Reset
is only possible if the power is turned off, and then on again.
