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--Customer Installation Interfaces, Physical Media Dependent Specification, T1.646-1995. 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 Siemens 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 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

3. DC/DC Transceiver Standard PECL inputs and outputs Tx and Rx are DC coupled. 4. AC/AC PECL Transceiver Tx and Rx are AC coupled. Tx has differential 100 load. Signal Detect is PECL 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 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. 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 continuously low level. The transceiver contains a supervisory circuit to control 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.

Receiver
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 load. Rx has standard PECL output and is DC coupled. 2. AC/AC TTL Transceiver Tx and Rx are AC coupled. Tx has differential 100 load. Signal Detect is TTL compatible.

LASER SAFETY This single mode transceiver is a Class 1 laser product. It complies with IEC 825-1 and FDA 21 CFR 1040.10 and 1040.11. The laser Class 1 is guaranteed within the Absolute Maximum Ratings. Caution The use of optical instruments with this product will increase eye hazard! Usage Restrictions The optical ports of the modules should be terminated with an optical connector or with a dust plug.
Note Failure to adhere to the above restrictions could result in a modification that is considered an act of "manufacturing," and will require, under law, recertification of the modified product with the U.S. Food and Drug Administration (ref. 21 CFR 1040.10 (i)).
