DESCRIPTION This data sheet describes the Siemens single mode ATM transceiver, which complies to 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 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, 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 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, and 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 power control uses the output of the monitor PIN diode (mechanically built into 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 increase of the optical output power by more than 2dB. Aging control is possible using the bias monitor output (BIASMON). To build an IEC Class 1 laser system it is necessary to use an application circuit to switch off the laser if a fault occurs.

Note 1. For VCC-VEE (min., max.). 50% duty cycle. The supply current does not include the load drive current of the receiver output. Add max. 45 mA for the three outputs. Load is 50 to VCC-2 V.
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 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.

Notes 1. Minimum average optical power at which the BER is less than 1 x 10E-12. Measured with a 223-1 NRZ PRBS as recommended by ANSI T1E1.2, SONET OC-3, and ITU G.957 . 2. An increase in optical signal above the specified level will switch the SIGNAL DETECT output to switch from a Low state to a High state. 3. A decrease in optical signal below the specified level will switch the SIGNAL DETECT to change from a High state to a Low state. 4. Measured by switching the light from <-40 dBm to -25 dBm. 5. Measured by switching the light from -25 dBm to <-40 dBm. Switching from higher power levels increases this time. 6. PECL compatible. Load is 50 into Vcc-2 V. Measured under DC conditions at 25C. For dynamic measurements a tolerance of 50 mV should be added. VCC=5 V. 7 PECL compatible. A high level on this output shows that an optical . signal is applied to the optical input.
