MAX3643
155Mbps to 2.5Gbps Burst-Mode Laser Driver
General Description
The MAX3643 burst-mode laser driver provides bias and
modulation current drive for PON burst-mode ONT appli-
cations. It is specifically designed for use with a low-cost
external controller for the APC (and if desired, AMC) loop.
A high-speed differential burst-enable input enables the
driver to switch the laser from a dark (output off) condition
to full on-condition in less than 2ns. When BEN is inac-
tive, typical modulation and bias currents are 5μA each.
Laser modulation current can be set from 10mA to
85mA and bias current can be set from 1mA to 70mA
using the MODSET and BIASSET inputs. A sample-and-
hold circuit is provided to capture the monitor diode

output during short PON bursts, if needed, and the BEN
high-speed signal is mirrored on an LVCMOS output to
be used by the controller operating the APC/AMC loop.
