MAX3867ECM
+3.3V / 2.5Gbps SDH/SONET Laser Driver with Automatic Power Control
General DescriptionThe 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.

unless otherwise noted.) (Note 1)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1:Characteristics at -40°C guaranteed by design and characterization. Dice are tested at TA= +25°C only.
Note 2:Tested at RMODSET= 2.49kΩ, RBIASMAX= 1.69kΩ, excluding IBIASand IMOD.
Note 3:Voltage on BIAS pin is (VCC- 1.6V).
Note 4:Both the bias and modulation currents will be switched off if any of the current set pins are grounded.
Note 5:Accuracy refers to part-to-part variation.
Note 6:Assuming that the laser to monitor-diode transfer function does not change with temperature.
