General Description
The MAX3669 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 temperature range from -40°C to +85°C.
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 MOD-
MON with current proportional to laser modulation.
The MAX3669 also provides enable control and a failure-
monitor output to indicate when the APC loop is unable to
maintain the average optical power. The MAX3669 is
available in a 5mm 32-pin TQFP package as well as in
dice.
