The MAX3667 is a complete, +3.3V laser driver with automatic power control (APC), designed for SDH/
SONET applications up to 622Mbps. It accepts differential 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 programming of the modulation current between 5mAP-P and 60mAP-P, and of the bias current between 5mA and 90mA.
The APC function, which incorporates a monitor photodiode, 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.
