155Mbps to 2.5Gbps Burst-Mode
Laser Driver
General Description
Features
The MAX3656 is a burst-mode laser driver that oper-
ates at data rates from 155Mbps up to 2.5Gbps. The
laser driver accepts either positive-referenced emitter-
coupled logic (PECL) or current-mode logic (CML) data
inputs and provides bias and modulation current for the
laser diode. The device can switch the laser diode from
a completely dark (off) condition to a full (on) condition
(with proper bias and modulation currents) in less than
2ns. The MAX3656 incorporates DC-coupling between
laser driver and laser diode and operates with a single-
supply voltage as low as +3.0V.
A digital automatic power-control (APC) loop is provided
to maintain the average optical power over the full tem-
perature range and lifetime. The APC loop is functional
for a minimum burst on-time of 576ns and minimum
burst off-time of 96ns, with no limit on the maximum
burst on- or off-time. A fail monitor is provided to indi-
