DESCRIPTION
The Infineon single mode ATM transceiver complies with the
ATM Forum's Network Compatible ATM for Local Network
Applications
document and ANSI's Broadband ISDN--Cus-
tomer Installation Interfaces, Physical Media Dependent Speci-
fication
, 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 multimedia 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 Telecommunications Union
(ITU), the former International Telegraph and Telephone Consul-
tative 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 Mbit/s 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 optical data is
present
(1)
.
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 prevent 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.
Note
1. We recommend to switch off the transmitter supply (V
CC
-Tx) if no
transmitter input data is applied.

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 622 MBd ATM 1x9 Transceiver, DC/DC Version
The following Application Notes assume Fiber Optic
Transceivers 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
manufacturer 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. Further applica-
tion notes for electrical interfacing are available upon request.
Ask for Appnote 82.
We strongly recommend a V
EE
plane under the module for get-
ting good EMI performance.
The transceiver contains an automatic shutdown circuit. Reset
is only possible if the power is turned off, and then on again.
