DESCRIPTION

The Infineon single mode ATM trans c eiver complies with the

ATM Forum’s Network Compati ble AT M for Local Network

Applications document and ANSI’s Broadb and ISDN -

Customer Installation Interfaces, Physical Media Dependent

Specification, T1.646-1995, Bellcore-SONET OC-3/LR-1 and

ITU-T G.957 STM-1/L.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 protocol is the basis of the bro adband public net-

works being standardized in the International Telecommunica-

tions Union (ITU), th e former International Telegraph an d

Telephone Cons ultative Committee (CCITT). AT M can also be

used in local private applications.

The Infineon single mode ATM lo ng haul transceiver is a single

unit comprised of a transmitter, a receiver, and an SC recepta-

cle. This de sign frees the customer from many alignment and

PC board layout concerns. The module is designed for low cost

WAN applicat ions. 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, inte lli-

gent hubs, and wide area AT M switches.

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

supply (+5 V or +3.3 Volt). The differential data inputs and out-

puts are PECL compatible.

Functional Description

This transceiver is designed to transmit serial data via single

mode cable.

Functional Diagram

The transmitter converts electrical PECL compatible serial data

(TD and TDno t) into optical serial data. It 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 prev ent the laser power from e xceeding the operating

limits.

This transceiver contains an Input Signal Mo nitor (ISM), that

switches the optical power off if a continuously low level is

applied at Data Input.

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).

This module is a Class 1 laser prod uct, due to an integrated

automatic shutdown circuit that disables the laser when it

detects transmitter failures.

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 ci rcuit to monitor the

power supply. This circuit makes an internal reset signal when-

ever the supply voltage drops below t he reset threshold. It

keeps the reset signal active for at least 15 milliseconds after

the voltage has risen ab ove the reset threshold. During this

time the laser is inactive.

Note

1. We recom me n d to switch off the transmi tter supply (VCC-Tx) if no

transmitter input data is applied.

TECHNICAL DATA

The electro-optical characteristics described in the following

tables are valid only for use under t he recommended operating

conditions.

Recommended Operating Conditions

Note

1. For VCC–VEE (min., max.). 50% duty cycle. The supply current does

not include the load drive current of the receiver output.

Transmitter 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 af ter tRES.

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

mask patt er ns .

Recei ver Electro-Opti c al Character i s tic s

Notes

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

1x10-10. Measured with a 223-1 NRZ PRBS as recommended 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 for data, DC/DC PECL for Signal Detect, PECL compatible.

Load is 50 Ω int o VCC –2 V for data, 500 Ω to VEE for Signal Detect.

Measured under DC conditions. For dynamic measurements a toler-

ance of 50 mV should be added. VCC=3.3 V / 5 V. TAMB=25°C.

5. PECL com patible. A high level on this output shows that an optical

signal is applied to the optical input.

APPLICATION NOTE

Single Mode 155 MBd ATM 1x9 Long Haul Transceiver

This Application Note assumes Fiber Optic Transceivers using

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

It al so as sume s no self bias ing a t the r ec eiv e r da ta inpu ts (RD+/

RD-) of the SerDes chip (Refer to the manufacturer data sheet

for other applications). 3.3 V-Transceivers can be directly con-

nected to SerDes-Chips using standard PECL Termination

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 f iltering

is required for good EMI performance. Use short tracks from

the inductor L1/L2 to the m odule 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-

ting good EMI performance.

The transceiver contain s an automatic shutdown circuit. Reset

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

(VCCTx switched below VTH).
