DESCRIPTION
Functional 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—Customer Installation Interfaces, Physical Media Dependent Specification, T1.646-1995, Bellcore - SONET OC-3 / IR-1 and
ITU-T G. 957 STM-1 / S.1.1.
This transceiver is designed to transmit serial data via single
mode cable.
Functional Diagram
Signal Monitor and
Automatic Shut-Down
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 Consultative Committee (CCITT). ATM can also be
used in local private applications.

Control
The Infineon single mode ATM transceiver is a single unit comprised 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 intelligent hubs, as well as wide area ATM switches.

Receiver
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).
This transceiver operates at 155.520 Mbit/s from a single power
supply (+5 Volt or 3.3 Volt). The differential data inputs and outputs are PECL compatible.
The transmitter converts electrical PECL compatible serial data
(TD and TDnot) into optical serial data.
This version contains an Input Signal Monitor (ISM), that
switches the optical power off if a continuously low level is
applied at Data Input.
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 output 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 (VCC-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

It is recommended that the Tx plug and the Rx plug be
separated with a bar that divides the duplex SC opening.
