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/LR-1 and ITU-T G.957 STM-1/L.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 long haul 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,
intelligent hubs, and 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 PECL compatible.
Functional Description
This transceiver is designed to transmit serial data via single mode cable.

Description
The transmitter converts electrical PECL compatible serial data (TD and TDnot) into
optical serial data. It 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.
This transceiver contains an Input Signal Monitor (ISM), that switches the optical power
off if a continuously low level is applied at Data Input.
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 module is a Class 1 laser product, due to an integrated automatic shutdown circuit
that disables the laser when it detects transmitter failures.
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 monitor the power supply. This circuit
makes 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.
1)
We recommend to switch off the transmitter supply (VCC - Tx) if no transmitter input data is applied.

Minimum average optical power at which the BER is less than 1x10-10. Measured with a 223 - 1 NRZ PRBS as
recommended by ANSI T1E1.2, SONET OC-3, and ITU-T G.957.
An increase in optical power of data signal above the specified level will cause the SIGNAL DETECT to switch
from a Low state to a High state.
A decrease in optical power of data signal below the specified level will cause the SIGNAL DETECT to switch
from a High state to a Low state.
DC/DC for data, DC/DC PECL for Signal Detect, PECL compatible. Load is 50 Ω into VCC – 2 V for data, 500 Ω
to VEE for Signal Detect. Measured under DC conditions. For dynamic measurements a tolerance of 50 mV
should be added. VCC = 3.3 V / 5 V. TAMB = 25°C.
PECL compatible. A high level on this output shows that an optical signal is applied to the optical input.

Application Notes
Application Notes
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 Notes
This Application Note assumes 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 Ω termination to VEE or 100 Ω differential
is provided. The power supply filtering is required for good EMI performance. Use short
tracks from the inductor L1/L2 to the module VCCRx/VCCTx. Further application notes for
electrical interfacing are available upon request. Ask for Appnote 82.
We strongly recommend a VEE 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. (VCCTx switched below VTH).
Application Board available on request.
