Description

Data Sheet 3 2000-12-19

Description

The Infineon multi mode transceiver is based on the Physical Medium Depend (PMD)

sublayer and baseband medium, type 1000BASE-SX (Long 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 multi mode 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.

Functional Description

This transceiver is designed to transmit serial data via multimode cable.

The receiver component converts the optical serial data into PECL compatible electrical

data (RD and RDnot). The Signal Detect (SD, active high) shows whether an optical

signal is present.

The transmitter converts electrical PECL compatible serial data (TD and TDnot) into

optical serial data.

The following versions are available:

1 AC/DC Transceiver: Tx is AC coupled. Differential 100 W load. Rx has standard PECL

output and is DC coupled.

2 AC/AC TTL Transceiver: Tx and Rx are AC coupled. Tx has differential 100 W load.

Signal Detect is TTL compatible.

3 DC/DC Transceiver: Standard PECL inputs and outputs Tx and Rx are DC coupled.

4 AC/AC PECL Transceiver: Tx and Rx are AC coupled. Tx has differential 100 W load.

Description

Data Sheet 5 2000-12-19

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

Data Sheet 10 2000-12-19

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).

Figure 5

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 W termination to VEE or 100 W 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).
