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.
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.
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.
This transceiver operates at 155.520 Mbit/s from a single power supply (5 V or 3.3 V).
The differential data inputs and outputs are DC-coupled and PECL compatible.

Functional Description
This transceiver is designed to transmit serial data via single mode fiber.
Figure 2
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 optical data is
present
1)
.
The transmitter converts electrical PECL compatible 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 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 or when
V
CC
is too high. A reset
is only possible by turning the power off, and then on again.

We recommend to switch off the transmitter supply (
