DESCRIPTION

The Infineon multi mode transceiver is based on the Physical

Medium Depend (PMD) sublayer and baseband medium, type

1000 BASE-SX (Long Wavelength Laser) (IEEE 802.3z) and com-

plies 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 multi-

mode fiber with Duplex SC connector.

The Infineon mult i mode transceiver is a single unit compr ised

of a transmitter, a receiver, and an S C receptacle. This design

frees the customer from many alignment and PC board layout

concerns.

The module is designed for low cost LAN, WAN, Gigabit Ether-

net, and Fibre Channel applicati ons. It can be used as the net-

work 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 Gb it/s and 1.3 Gbit /s from a

single power supply (+5 Volt or 3.3 Volt). The full different ial

data i nputs and outputs are PECL compatible.

Operatin g range each optical fiber type at 1.0625 GBd

Functional Description

This transceiver is designed to transmit serial data via multi-

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 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. Dif f erential 1 00 Ω load. Rx h as standa rd PE CL

outpu t and is DC coupled.

2. AC/AC TTL Transceiver

Tx and Rx are AC coupled. Tx has diff e rential 1 00 Ω load. Signal

Detect is TT L 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 diff e rential 1 00 Ω load. Signal

Detect is PECL compatible.

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 prev ent the laser power from e xceeding the operating

limits.

Single fault condition is ensu red 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 NOTE

Gigabit transceivers and matching cir c uits are high freque ncy

components and shall be terminated as recommended in the

appl ic a tio n not es for pr op er EMI p er formanc e. Electr o ma g ne t ic

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 str ongl y r eco mmen de d that the Tx plug and the R x plug be

separated with a bar that divides the duplex SC opening.

If sh ielded parts are emp loy ed, the y should be in pr oper con tact

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 c ircuitry i.e. even any ground connection on the pcb

may be harmful to EMI performa nc e.

In ca ses wh ere EMI pe rf orm ance be comes crit ical it has p ro ven

to be helpful when using SC -plugs with less metal parts inside

(as Infineon fibers).

APPLICATION NOTE

Multi mode 850 nm Gigabit Ethernet/Fibre Channel 1x9 Transceiver, DC/DC Version

This Application Note assumes Fiber Optic Transceivers using

5 V power supply and SerDes Chips using 3.3 V power supply.

It also assum es self biasing at the re ceiver data inputs (RD+/

RD–) of the SerDes chip . Refer to the manufacturer data sheet

for other applications. 3.3 V-Trans ceivers can be directly con -

nected to SerDes-Chips using standard PECL Termination

network.

Value of R1 ma y v ary a s long as pr oper 50 Ω termination to V EE

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).
