MAX3669
+3.3V, 622Mbps SDH/SONET
Laser Driver with Current Monitors and APC
General Description
Features
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 MODMON
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
