+3.3V, 622Mbps SDH/SONET

Laser Driver with Current Monitors and APC

General Description

Features

The MAX3663 is a complete, +3.3V laser driver with auto-

matic power-control (APC) circuitry for SDH/SONET appli-

cations up to 622Mbps. It accepts differential PECL

inputs, provides bias and modulation currents, and oper-

ates over a -40°C to +85°C temperature range.

ꢀ +3.3V or +5.0V Single-Supply Operation

ꢀ 40mA Supply Current at +3.3V

ꢀ Programmable Bias Current from 1mA to 80mA

ꢀ Programmable Modulation Current from

5mA to 75mA

ꢀ Bias Current and Modulation Current Monitors

ꢀ 200ps Rise/Fall Time

ꢀ Automatic Average Power Control with Failure

Monitor

ꢀ Complies with ANSI, ITU, and Bellcore

SONET/SDH Specifications

An APC feedback loop is incorporated to maintain a

constant average optical power over temperature and

lifetime. The wide modulation current range from 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. Two pins are provided to

monitor the current levels in the laser: BIASMON with

current proportional to laser bias current, and MODMON

with current proportional to laser modulation.

ꢀ Enable Control

The MAX3663 also provides enable control and a failure-

monitor output to indicate when the APC loop is unable

to maintain the average optical power. The MAX3663

is available in a compact 4mm x 4mm 24-pin thin QFN

package.
