Description Single Mode OC 12 Long Haul ATM Transceiver 1 x 9 Part Number V23806-A84-C72
Description
This data sheet describes the Siemens single mode ATM transceiver, which 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 is being 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 Consultive 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. It thereby 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 622.080 Mbits per second from a single power supply (+5 Volt). The full differential data inputs and data and clock outputs are PECL compatible.

Functional Descriptionof 1x9 Pin Row Transceiver
The Transceiver is designed to transmit serial data via single mode cable. Functional Diagram:
The receiver component converts the optical serial data into ECL-compatible electrical data (RD and RDnot). The Signal Detect (SD, active high) shows whether a optical signal is present. If no optical input signal is present the receiver data outputs are switched to static low level (RD = Low, Rdnot = high). The transmitter converts electrical ECL compatible serial data (TD and TDnot) into optical serial data. It contains a laser driver circuit which drives the modulation and bias current of the laser diode. The currents are controlled by a power control circuit to guarantee a constant output power of the laser over temperature and aging. The power control uses the output of the monitor pin diode (mechanically built in the laser coupling unit) for the controlling function to prevent the laser power from exceeding the operating limits. This module ensures single fault condition with an integrated automatic shutdown circuit, which disables the laser when it detects transmitter failures. A reset is only possible by turning the power off, then on again. The transceiver contains a supervisiory circuit to control the power supply. This circuit makes an internal reset signa whenever the supply voltage declines below the reset threshold. It keeps the reset signal active for at least 140 milliseconds after the voltage has risen above the reset threshold. During this time the laser is inactive.
