General Desc ription
The MAX3867 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. The synchronizing input latch can be bypassed if
a clock signal is not available.
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 MAX3867 also provides enable control, a program-
mable slow-start circuit to set the laser turn-on delay,
and a failure-monitor output to indicate when the APC
loop is unable to maintain the average optical power.
The MAX3867 is available in a small 48-pin TQFP pack-
age as well as dice.
