Description
Description
The Infineon multimode transceiver is based on the Physical Medium Depend (PMD)
sublayer and baseband medium, type 1000-Base-SX (Short Wavelength Laser)
(IEEE 802.3z) and complies with the Fibre Channel Physical and Signaling Interface
(FC-PH), ANSI XSI TT Fibre Channel Physical Standard Class 100-M5-SLI, latest
revision.
The appropriate fiber optic cable is 62.5 µm or 50 µm multimode fiber with Duplex SC
connector.
The Infineon multimode 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, WAN, Gigabit Ethernet, and Fibre Channel
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, intelligent hubs, and local and wide area switches.
This transceiver operates at 1.0625 Gbit/s and 1.3 Gbit/s from a single power supply
(5 V or 3.3 V). The full differential data inputs and outputs are PECL compatible.

V23826-K305-Cxx/Cxxx
Description
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 transmitter failures. A reset is only possible by
turning the power off, and then on again.
The transceiver contains a supervisory circuit to control the power supply. This circuit
generates 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.

Application Notes
Application Notes
Gigabit transceivers and matching circuits are high frequency components and shall be
terminated as recommended in the application notes for proper EMI performance.
Electromagnetic emission may be caused by these components.
To prevent emissions it is recommended that cutouts for the fiber connectors be
designed as small as possible.
It is strongly recommended that the Tx plug and the Rx plug be separated with a bar that
divides the duplex SC opening.
If shielded parts are employed, they should be in proper contact with the bezel (back
plane).
Since the shield is galvanically isolated from signal ground it is strongly recommended
to prevent any contact between shield and the circuitry i.e. even any ground connection
on the pcb may be harmful to EMI performance.
In cases where EMI performance becomes critical it has proven to be helpful when using
SC-plugs with less metal parts inside (as Infineon fibers).

This Application Note assumes Fiber Optic Transceivers using 5 V power supply and
SerDes Chips using 3.3 V power supply. It also assumes self biasing at the receiver data
inputs (RD+/RD–) of the SerDes chip. Refer to the manufacturer data sheet for other
applications. 3.3 V-Transceivers can be directly connected to SerDes-Chips using
standard PECL Termination network.
Value of R1 may vary as long as proper 50 Ω termination to VEE or 100 Ω differential is
provided. The power supply filtering is required for good EMI performance. Use short
tracks from the inductor L1/L2 to the module VCCRx/VCCTx.
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).
