MAX3865 Datasheet (Maxim) - 2.5Gbps Laser Driver with Automatic Modulation Control

MAX3865, 2.5Gbps Laser Driver with Automatic Modulation Control

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 extinction ratio over temperature and
