General Description
The MAX3865 is designed for direct modulation of laser
diodes at data rates up to 2.5Gbps. It incorporates two
feedback loops, the automatic power-control (APC)
loop and the automatic modulation-control (AMC) loop,
to maintain constant average optical output and extinc-
tion ratio over temperature and laser lifetime. External
resistors or current output DACs may set the laser out-
put levels. The driver can deliver up to100mA of laser
bias current and up to 60mA laser modulation current
with a typical (20% to 80%) edge speed of 84ps.
The MAX3865 accepts differential clock and data input
signals with on-chip 50
termination resistors. The inputs
can be configured for CML or other high-speed logic. An
input data-retiming latch can be enabled to reject input
pattern-dependent jitter when a clock signal is available.
The MAX3865 provides laser bias current and modulation
current monitors, as well as a failure detector, to indicate
the laser operating status. These features are all imple-
mented on an 81mil
103mil die; the MAX3865 is also
available as a 32-pin QFN package.
