DESCRIPTION

The Infineon single mode ATM transceiver c omplies with the

ATM Forum’s Network Compatible ATM for Local Network

Applications document and ANSI’s Broadband ISDN—Cus-

tomer Installation Interfaces, Physical Media Dependent Sp eci-

fication, T1.646-1995, Bellcore - SONET OC-3 / IR-1 and

ITU-T G. 957 STM-1 / S.1.1.

ATM was developed to facilitate solutions in multimedia appli-

cations and real time transmission. The data rat e is scalable,

and the ATM protoc ol is the basis of the broadband public n et-

works being standardized in the International Telecommunica-

tions Union (ITU), th e former International Telegraph and

Telep hone Co nsultative Committee (CCITT). ATM can also be

used in local private applications.

The Infineon single mode ATM transceiver is a single unit com-

prised of a tran smitter, 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 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 devices such as bridges, routers, and intelli-

gent hubs, as well as wide area ATM switches.

T his tr ansceiv er oper ates a t 1 55.520 Mb it/s fr om a sing le pow er

supply ( +3.3 Volt). The 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 ele ctrical PECL compatible serial data

(TD and TDnot) into optical serial data.

This version contains an I nput Signal Moni tor (ISM), that

switches the optical power off if a cont inuously low level is

applied at Data Input.

The transmitter cont ain s 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 fa ilures. A reset is only possible by turning

the power off, and then on again.

The transceiver contains a supervisory circuit to control the

power s upply. 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 15 milliseconds after

the voltage has risen above the reset threshold. During this

time the laser is i nactive.

Note

1. We recomme nd to switch off the transmitter supply (VCC-Tx) if no

transmitter input data is applied.

TECHNICAL DATA

The electro-optical characteristics described in the following

tables are only valid for use under t he recommended operating

conditions.

Recommen ded Operating Conditions

Note

1. For VCC–VEE (min., max . ) 5 0 % duty cycle. The su pply c urr en t does

not include the load drive current of the receiver output.

Transmi tter Electro-Optical Characteristics

Notes

1. Into single mode fiber, 9 µm diameter.

2. Laser power is shut down if power supply is below VTH and

switched on if power supply is above VTH after tRES.

3. Transmitter meets ANSI T1E1.2, SONET OC-3 and ITU-T G.957 mask

patterns.

Receiver Electro-Optical Characteristics

Notes

1. Minimum average optical power at which the BER is less than

1x10-10 or lower. Measured with a 223-1 NRZ PRBS as recom-

mended by ANSI T1E1.2, SONET OC-3 and ITU-T G.957.

2. An increase in optical power of data signal above the specified level

will cause the SIGNAL DETECT to switch from a Low state to a High

state.

3. A decrease in optical power of data signal below the specified level

will cause the SIGNAL DETECT to switc h from a High state to a L o w

state.

4. DC/DC, PECL for Signal Detect

PECL compatible. Load is 50 Ω into VCC –2 V for data, 500 Ω to VEE

for Signal Detect. Measured under DC conditions. For dynamic mea-

surements a tolerance of 50 m V should be added. VCC=3.3 V.

APPLICATION NOTE

ATM transceivers and matching circuits are high frequency

compone nts and sha ll be terminated as recomm ended in the

application notes for pr oper EMI perf ormance. 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 recommended that the Tx plug and the Rx plug be

separated with a bar that divides the duplex SC opening.

3.3 V-Transceivers can be directly connected to SerDes-Chips

using stan dard PECL Terminat ion network.

Value of R1...R4 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. F urther applica-

tion notes for electrical interfacing are available upon request.

Ask for Appnote 82.

We strongly recommend a VEE plane under the module for get-

The transceiver contains an automatic shutdown circuit. Reset

is only possible if the power is turned off, and then on again.
