+3.3V, 2.5Gbps SDH/SONET Laser Driver
with Current Monitors and APC
General Description
The MAX3869 is a complete, single +3.3V laser driver
for SDH/SONET applications up to 2.5Gbps. The
device accepts differential PECL data and clock inputs
and provides bias and modulation currents for driving a
laser. A synchronizing input latch can be used (if a
clock signal is available) to reduce jitter.
An automatic power control (APC) feedback loop is
incorporated to maintain a constant average optical
power over temperature and lifetime. The wide modula-
tion current range of 5mA to 60mA and bias current of
1mA to 100mA are easy to program, making this prod-
uct ideal for use in various SDH/SONET applications.
The MAX3869 also provides enable control, two current
monitors that are directly proportional to the laser bias and
modulation currents, and a failure-monitor output to indi-
cate when the APC loop is unable to maintain the average
optical power. The MAX3869 is available in 32-pin TQFP
and small 32-pin QFN packages as well as dice.
