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, T1E1.2. 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 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. It thereby frees the customer from many alignment and PC board layout concerns. The module is designed for low cost LAN and 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, as well as local and wide area ATM switches. This transceiver operates at 155.520 Mbits per second from a single power supply (+5 Volt). The full differential data inputs and outputs are PECL compatible.

Functional Description of 2x9 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. 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 PECL 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. The laser can be switched on with a logical high signal on the Laser Enable Pin (LEN). The PWRMON Pin shows a voltage reflecting the optical power output. The bias current is monitored on the BIASMON Pin. Both signals can be used to supervise the function of the module. The signal TXALM indicates an increasing of the optical output power of more than 2dB. Aging control is possible using the bias monitor output (BIASMON). To build a Class 1 laser system it is necessary to use an application circuit to switch off the laser if a fault occurs.
