CX02068

622 Mbps, 3.3V Laser Driver

Overview

Description

The CX02068 is a highly integrated, programmable laser driver intended for telecom applications up to 622 Mbps. Using differential PECL data and clock inputs, the CX02068 supplies the bias and modulation current for driving an edge-emitting laser. The modulation output can be DC-coupled to the laser diode, giving a significant power savings over AC-coupled operation. The modulation current is temperature-compensated to minimize the variation in extinction ratio over temperature.

Features

Rise and fall times <180 ps
DC- or AC-coupled modulation drive
Independently programmable laser bias and modulation currents
Bias current to 100 mA and modulation current to 85 mA at VCC = 3.3 V
Automatic laser power control with programmable temperature compensation and 'slow-start'
Bias and modulation current monitors
Operates with +3.3 V supply
Low-cost CMOS
Output flags indicate laser end-of-life and APC failure
Available in die form and BCC24 packages
