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.
Functional Diagram
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 sig-
nal, 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 (V
CC
-Tx) if no
transmitter input data is applied.
