• Manufacturer Part Number: v23826-h18-c13
• Description: Single Mode 1300 Nm 622 Mbd Atm 1x9 Transceiver
• Manufacturer: Infineon Technologies Corporation

DESCRIPTION
The Siemens single mode ATM transceiver complies with the
ATM Forum’s Network Compatible ATM for Local Network
Applications document and ANSI’s Broadband ISDN—Cus-
tomer Installation Interfaces, Physical Media Dependent Speci-
fication , T1.646-1995.
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 Siemens single mode ATM transceiver is a single unit com-
prised 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 intelli-
gent hubs, as well as wide area ATM switches.
This transceiver operates at 622.080 Mbits per second from a
single power supply (+5 Volt or 3.3 Volt). The full differential
data inputs and outputs are PECL compatible.
Functional Description of 1x9 Pin Row Transceiver
This transceiver is designed to transmit serial data via single
mode cable.
Functional Diagram
The receiver component converts the optical serial data into
PECL compatible electrical data (RD and RDnot). The Signal
Detect (SD, active high) shows whether an optical signal
is present.
The transmitter converts electrical PECL compatible serial data
(TD and TDnot) into optical serial data.
The following versions are available:
1. AC/DC Transceiver
Tx is AC coupled with differential 100
PECL output and is DC coupled.
2. AC/AC TTL Transceiver
Tx and Rx are AC coupled. Tx has differential 100
Detect is TTL compatible.

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 pre-
vent 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 DC/DC transceiver contains a data input monitor, that
switches the transmitter off when Data Input receives at a con-
tinuously low level.
The transceiver contains a supervisory circuit to control the
power supply. This circuit makes an internal reset signal when-
ever 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.
