DESCRIPTION
The Infineon Gigabit Ethernet multimode transceiver – part of
Infineon Small Form Factor transceiver family – is based on the
Physical Medium Depend (PMD) sublayer and baseband
medium, type 1000BASE-SX (short wavelength), Fibre Channel
FC-PI 100-M5-SN-I, 100-M6-SN-I
FC-PH2 100-M5-SN-I, FC-PH2 100-M6-SN-I.
The appropriate fiber optic cable is 62.5 µm or 50 µm multi-
mode fiber with LC™ connector.
Operating range for over each optical fiber type
The Infineon Gigabit Ethernet multimode transceiver is a single
unit comprised of a transmitter, a receiver, and an LC™ recepta-
cle. This design frees the customer from many alignment and
PC board layout concerns.
This transceiver supports the LC™ connectorization concept.
It is compatible with RJ-45 style backpanels for high end
Data Com and Telecom applications while providing the advan-
tages of fiber optic technology.
The module is designed for low cost SAN, LAN, WAN, Fibre
Channel and Gigabit Ethernet applications. It can be used as the
network end device interface in mainframes, workstations,
servers, and storage devices, and in a broad range of network
devices such as bridges, routers, hubs, and local and wide area
switches.
This transceiver operates at 1 and 1.25 Gbit/s from a single
power supply (+3.3 V). The full differential data inputs and out-
puts are PECL and LVPECL compatible.

Functional Description of 2x5 Pin Row Transceiver
This transceiver is designed to transmit serial data via
multimode cable.
Functional Diagram
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 differen-
tially 100
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 out-
put 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 when-
ever 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.
A low signal on TxDis enables transmitter. If TxDis is high the
transmitter is disabled.
