The MAX3667 is a complete, +3.3V laser driver with

automatic power control (APC), designed for SDH/

SONET applications up to 622Mbps. It accepts differ-

ential PECL inputs, provides single-ended bias and

modulation currents, and operates over a -40°C to

+85°C temperature range.

A temperature-stabilized reference voltage simplifies

laser current programming. It allows external program-

ming of the modulation current between 5mA

60mA

90mA.

The APC function, which incorporates a monitor photo-

diode, an external resistor, and two external capacitors,

maintains constant laser output power. Two current

monitors provide high-speed signals that are directly

proportional to the bias and modulation currents.

Additional features include disable/enable control and

a slow-start feature with a minimum turn-on time of

50ns. The MAX3667 is available in die form and in a

32-pin TQFP package.

19-1311; Rev 3; 1/03
