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.

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.

This 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, and wide area ATM switches.

RxPMon
The receiver component converts the optical serial data into
PECL compatible electrical data (RxD and RxDn). The Signal
Detect (SD, active high) shows whether an optical signal is
present(1). If no optical input signal is present the receiver data
outputs are switched to static low level (RxD=0, RxDn=high).
This transceiver operates at 155.52 Mbit/s from a single power
supply (+3.3 V). The differential data inputs, data outputs and
signal detect output are PECL compatible.
This transceiver offers the advantage of an analog Rx power
monitor (RxPMON) that can prove and control link status,
including transmission distances and security of the connection. This output shows an analog voltage that is proportional to
the light input within the range of -20 dBm to -30 dBm.
The transmitter part converts electrical PECL compatible serial
data (TxD and TxDn) 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.
The laser can be switched off with a high signal on the Transmitter Disable pin (TxDis). The TxPMon pin shows a voltage
reflecting the optical power output. The bias current is monitored on the BIASMON pins. Both signals can be used to supervise the function of the module.
Aging control is possible using the bias monitor output (BIASMON). The module has an integrated shutdown function that
switches the laser off in the event of an internal failure.
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.

* Recommended choke is Siemens Matsushita B78108-S1153-K or B78148-S1153-K (Qmin=60, max. DC resistance =0.6 Ω).
The power supply filtering is recommended for good EMI performance. Use short tracks from the inductor L1/L2 to the module VCC-Rx/VCC-Tx. We recommend a VEE plane under the
module for getting good EMI performance. The transceiver contains an automatic shutdown circuit. Reset is only possible
when the power is turned off, and then on again (VCCTx = 0 V).
The receiver data signals should be terminated with 50 Ω at the
far end. Terminations should be placed very close to the
receiver data pins in combination with AC coupling.
