General Description
The MAX3668 is a complete, +3.3V laser driver with
automatic power control (APC) circuitry for SDH/SONET
applications up to 622Mbps. It accepts differential
PECL inputs, provides bias and modulation currents,
and operates over a temperature range of -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 of 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.
The MAX3668 also provides enable control and a failure-
monitor output to indicate when the APC loop is unable
to maintain the average optical power. The MAX3668 is
available in a 5mm 32-pin TQFP package as well as in
dice.
