+3.3V, 622Mbps SDH/SONET

Laser Driver with Automatic Power Control

General Description

Features

The MAX3668 is a complete, +3.3V laser driver with

automatic power control (APC) circuitry for SDH/SONET

applications up to 622Mbps. It accepts differential

PECL inputs, provides bias and modulation currents,

and operates over a temperature range of -40°C to

+85°C.

♦ Single +3.3V or +5.0V Operation

♦ 38mA Supply Current at +3.3V

♦ Programmable Modulation Current from

5mA to 75mA

♦ Programmable Bias Current from 1mA to 80mA

♦ Rise/Fall Time <200ps

An APC feedback loop is incorporated to maintain a

constant average optical power over temperature and

lifetime. The wide modulation current range of 5mA to

75mA and bias current of 1mA to 80mA are easy to

program, making this product ideal for use in various

SDH/SONET applications.

♦ Automatic Average Power Control with Failure

Monitor

♦ Complies with ANSI, ITU, and Bellcore

The MAX3668 also provides enable control and a failure-

monitor output to indicate when the APC loop is unable

to maintain the average optical power. The MAX3668 is

available in a 5mm 32-pin TQFP package as well as in

dice.
