MAX3869
+3.3V, 2.5Gbps SDH/SONET Laser Driver with Current Monitors and APC
High-Performance, Full-Featured Laser Driver
|
Status
Active: In Production.
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 modulation
current range of 5mA to 60mA and bias current of
1mA to 100mA are easy to program, making this product
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 indicate
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.
