DESCRIPTION This data sheet describes the Infineon Single Mode SC FDDI transceiver, which complies with the current Fiber Distributed Data Interface (FDDI) Single Mode Fiber Physical Layer Medium Dependent (SMF-PMD ANSI standard). The Infineon single mode SC FDDI 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 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 intermediate devices such as bridges, routers, intelligent hubs, and concentrators. This transceiver operates at 125 MBit/s from a single power supply (+5 Volt). The full differential data inputs and outputs are PECL compatible.
Functional Description This transceiver is designed to transmit serial data via single mode cable.

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 optical data is present(1). 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 in the laser coupling unit) as a controlling signal, to prevent the laser power from exceeding the operating limits. 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.
Note 1. We recommend to switch off the transmitter supply (VCC-Tx) if no transmitter input data is applied.

1. Minimum average power at which the BER is less than 2.5-10 or lower. Measured with the ANSI Worst Case pattern from Appendix 5 of the PMD. 2. An increase in optical power of data signal 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 of data signal below the specified level will cause the SIGNAL DETECT to switch from a High state to a Low state. 4. PECL compatible. Load is 50 into VCC-2 V. Measured under DC conditions. For dynamic measurements a tolerance of 50 mV should be added. VCC=5 V. 5. PECL compatible. A high level on this output shows that optical data is applied to the optical input. 6. Measurement done using the Idle Line state (62.5 MHz square wave). 7 Test method as in PMD Appendix A. All jitter values are peak. to-peak. 8. Measurement done using the Worst Case test pattern described in the PMD Appendix A.5. 9. Measurement done using the Idle Line state (62.5 MHz square wave).

* Recommended choke is Siemens Matsushita B78108-S1153-K or B78148-S1153-K (Qmin=60, max. DC resistance=0.6 ).
The power supply filtering is recommended for good EMI performance. Use short tracks from the inductor L1/L2 to the module VCC-RX/VCC-TX. We recommend a VEE plane under the module for getting good EMI and sensitivity performance. Studs should be connected to this VEE 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. Further application notes for electrical interfacing are available upon request. Ask for Appnote 82. Application board available on request.
