DESCRIPTION This data sheet describes the Siemens single mode ATM long haul transceiver. 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 long haul 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, intelligent hubs, 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 1x9 Pin Row Transceiver This transceiver is designed to transmit serial data via single mode cable. Functional Diagram
Automatic Shut-Down
LEN TD TD Laser Coupling Unit e/o
This module is a Class 1 laser product, due to an integrated automatic shutdown circuit that disables the laser when it detects transmitter failures. The transceiver contains a supervisory circuit to monitor 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 140 milliseconds after the voltage has risen above the reset threshold. During this time the laser is inactive. TECHNICAL DATA The electro-optical characteristics described in the following tables are valid only for use under the recommended operating conditions. Recommended Operating Conditions

RD RD SD
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. 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. 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.

Notes 1. Minimum average optical power at which the BER is less than 1x10E-10. 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 power above the specified level will cause the SIGNAL DETECT to switch from a Low state to a High state. 3. A decrease in optical power below the specified level will cause the SIGNAL DETECT to switch 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.

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 transceiver must be operated under recommended operating conditions. Caution The use of optical instruments with this product will increase eye hazard! Do not view into the open optical port for more than 60 seconds. General Restrictions Classification is valid only if the module is operated within the specified temperature and voltage limits. The system using the module must provide power supply protection that guarantees that the system power source will cease to provide power if the maximum recommended operation limit or more is detected on the +5 V at the power source. The case temperature of the module must be in the temperature range given in the recommended operating limits. These limits guarantee the laser safety. Usage Restrictions The optical ports of the modules shall 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)].

* Recommended choke is Siemens Matsushita B78108-S1153-K or B78148-S1153-K (Qmin=60, max. DC resistance =0.6 Ohm).
The power supply filtering is required for good EMI performance. Use short tracks from the inductor L1/L2 to the module VCC-RX/VCC-TX. A GND plane under the module is required for good EMI and sensitivity performance. Studs must be connected to this GND plane.
The transceiver contains an automatic shutdown circuit. Reset is only possible if the power is turned off, and then on again. VCCTX switched below VTH.
