DESCRIPTION
This data sheet describes the Infineon single mode ATM
transceiver, which 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, T1E1.2, Bellcore -
SONET OC-3/IR-1 and ITU-T G.957 STM1/S1.1.
ATM was developed to facilitate solutions in multimedia appli-
cations and real time transmission. The data rate is scalable,
and the ATM protocol is the basis of the broadband public net-
works being standardized in the International Telecommunica-
tions 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 LC receptacle. This
design frees the customer from many alignment and PC board
layout concerns. The module is designed for low cost LAN and
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 local and wide area ATM switches.
This transceiver operates at 155.520 Mbit/s from a single power
supply (+3.3 V). The full differential data inputs and outputs are
PECL compatible.

Functional Description of SFF 2x5 Pin Row Transceiver
This transceiver is designed to transmit serial data via single
mode fiber.
Functional Diagram
The receiver component converts the optical serial data into
PECL compatible electrical data (RD+ and RD–). The Signal
Detect (SD, active high) shows whether an optical signal is
present.
The transmitter converts PECL compatible electrical serial data
(TD+ and TD–) into optical serial data.
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 laser fault to guarantee the laser Eye Safety.
The transceiver contains a supervisory circuit to control the
power supply. This circuit makes an internal reset signal when-
ever the supply voltage (V
old (V
milliseconds after the voltage has risen above the reset thresh-
old. During this time the laser is inactive.
A low signal on TxDis enables transmitter. If TxDis is high or not
connected the transmitter is disabled.
