DESCRIPTION The Siemens single mode ATM transceiver 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 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.

This Siemens single mode ATM transceiver is a single unit comprised of a transmitter, a receiver, a clock recovery module, 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, and intelligent hubs, and wide area ATM switches. This transceiver operates at 622.080 Mbits per second from a single power supply (+5 Volt). The differential data inputs, data outputs, clock outputs and signal detect output are PECL compatible.

Note
The receiver component converts the optical serial data into PECL compatible electrical data (RxD and RxDn). It provides also a recovered in-phase clock and clock not signal. 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 part converts electrical PECL compatible serial data (TxD and TxDn) 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. The laser can be switched off with a logical high signal on the Transmitter Disable pin (TxDIS). The PWRMON pin shows a voltage reflecting the optical power output. The bias current is monitored on the BIASMON pins. Both signals can be used to supervise the function of the module. The signal TXALM (optional) indicates an increasing of the optical output power of more than 2dB. Aging control is possible using the bias monitor output (BIASMON). The module has an integrated shutdown function that switches the laser off in the event of an internal failure.

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
Discharges of 15kV with an air discharge probe on the receptacle cause no damage. With a field strength of 10 V/m rms, noise frequency ranges from 10 MHz to 1 GHz. No effect on transceiver performance between the specification limits.

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 +5V 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

* Recommended choke is Siemens Matsushita B78108-S1153-K or B78148-S1153-K (QPLQ=60, max. DC resistance =0.6 ).
The power supply filtering is required for good EMI performance. Use short tracks from the inductor L1/L2 to the module V&&-RX/V&&-TX. A GND plane under the module is required for good EMI and sensitivity performance. Studs should be connected to this GND plane. The transceiver contains an automatic shutdown circuit.
Reset is only possible when the power is turned off, and then on again (V&&TX=0 V), or by disabling the transmitter with TxDIS and enabling it after at least 500 ms. The receiver data signals should be terminated with 50 at the far end. 200 terminations should be placed very close to the receiver data pins in combination with AC coupling.
