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 Consultative Committee (CCITT). ATM can also be used in local private applications. This 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. The 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 Description of 2x9 Pin Row Transceiver This transceiver is designed to transmit serial data via single mode cable. Figure 1. Functional diagram
TxEN BIAS MON TxD TxD Laser Coupling Unit
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 laser Class 1 system it is necessary to use an application circuit to switch off the laser if a fault occurs. Recommended Operating Conditions

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. 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

Notes 1. Minimum average optical power at which the BER is less than 1x10E10. Measured with a 2231 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 switch the SIGNAL DETECT from a LO state to a HI state. 3. A decrease in optical signal below the specified level will switch the SIGNAL DETECT from a HI state to a LO state. 4. PECL 10K compatible. Load is 50 into VCC 2V. Measured under DC conditions at 25°C. For dynamic measurements a tolerance of 50 mV should be added, VCC=5V. 5. PECL compatible. A high level on this output shows that an optical signal is applied to the optical input.

LASER SAFETY This single mode ATM 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! General Restrictions Classification is only valid 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 +5V at the power source. The temperature of the module case 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)).

The shut down circuit checks the monitor voltage (PWRMON). A deviation of ± 0.5 V shuts down the laser in the circuit shown above. The transceiver can be reenabled using the reset circuit. 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 this GND plane.
