MB85R256PFTN Overview

2.7Gbps Laser Driver with Modulation Compensation

19-2281; Rev 2; 5/03
2.7Gbps Laser Driver with Modulation
Compensation
General Description
The MAX3863 is designed for direct modulation of laser
diodes at data rates up to 2.7Gbps. An automatic
power-control (APC) loop is incorporated to maintain a
constant average optical power. Modulation compensa-
tion is available to increase the modulation current in
proportion to the bias current. The optical extinction
ratio is then maintained over temperature and lifetime.
The laser driver can modulate laser diodes at ampli-
tudes up to 80mA. Typical (20% to 80%) edge speeds
are 50ps. The MAX3863 can supply a bias current up
to 100mA. External resistors can set the laser output
levels.
The MAX3863 includes adjustable pulse-width control
to minimize laser pulse-width distortion. The device
offers a failure monitor output to indicate when the APC
loop is unable to maintain the average optical power.
The MAX3863 accepts differential CML clock and data
input signals with on-chip 50Ω termination resistors. If a
clock signal is available, an input data-retiming latch
can be used to reject input pattern-dependent jitter.
The laser driver is fabricated with Maxim’s in-house
second-generation SiGe process.
