ADN2841 - Dual-Loop 50 Mbps.2.7 Gbps Laser Diode Driver

Datasheet Summary

Description

The ADN2841 uses a unique control algorithm to control both the average power and extinction ratio of the laser diode (LD) after initial factory setup.

Because power and extinction ratio control are fully integrated, external component count is low and PCB area is small.

Features

  • 50 Mbps to 2.7 Gbps operation Typical rise/fall time: 80 ps Bias current range: 2 mA to 100 mA Modulation current range: 5 mA to 80 mA Monitor photodiode current: 50 µA to 1200 µA Closed-loop control of power and extinction ratio Laser fail and laser degrade alarms Automatic laser shutdown (ALS) Dual MPD functionality for DWDM Optional clocked data Full current parameter monitoring 5 V operation 48-lead LFCSP 32-lead LFCSP (reduced functionality) Dual-Loop, 50 Mbps to 2.7 Gbps Laser Diode Drive.
