Infineon's BIDI-TRX is designed to handle multiple data rates and can be designed into Fast Ethernet, FDDI, Fiber Channel, ATM-155, SDH STM-1, SONET OC-3, CCTV and other applications as well as different FTTx applications according to the 100 Mbps EFM standard (IEEE 802.3ah). It is suitable for both, short haul applications and distances of 20 km and beyond. The appropriate fiber optic cable is the 9µm singlemode fiber pigtail with different connector options. The Infineon BIDI transceiver is a single unit comprised of a transmitter, a receiver, WDM filter, and a singlemode fiber pigtail. This design frees the customer from many alignment and PC board layout concerns. This transceiver operates at 155 Mbit/s from a single power supply (+3.3 V). The full differential data inputs and outputs are PECL and LVPECL compatible. Functional Description of 2x5 Pin Row Transceiver This transceiver is designed to transmit and receive serial data via a single mode cable. Figure2 Data Sheet Functional Diagram 4 2003-06-13 V23870-Ax131-xx00 V23870-Ax132-xx00 Description The receiver component converts the optical serial data into PECL compatible electrical data (RD+ and RD-). The Signal Detect (SD, active high) shows whether an optical signal is present. The transmitter converts PECL compatible electrical serial data (TD+ and TD-) into optical serial data. Data lines are differentially 100 Ohm terminated. The transmitter 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. Single fault condition is ensured by means of an integrated automatic shutdown circuit that disables the laser when it detects laser fault to guarantee the laser Eye Safety. The transceiver contains a supervisory circuit to control 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. The laser can be disabled by the TxDis input.
