UX 2208

155Mbps to 622Mbps Laser Driver

Features

General Description

+3.0V to +5.5V Supply Voltage

Automatic Power Control

The UX2208 is a complete CMOS laser driver for

155Mbps to 622Mbps.It consists of a bias current

generator with automatic power control (APC), a

modulation current driver and a reference

Temperature-Compensated Modulation

compensation. The UX2208 accepts differential

PECL inputs and provides complementary output

currents. The APC feature allows an optical

transmitter to maintain constant average optical

power by a monitor photodiode, despite changes

in laser efficiency with temperature and lifetime.

A temperature stabilized reference voltage is

provided to simplify laser current programming.

Utilizing a resistor at the I_MODTCpin can

compensate the reduction in slope efficiency of

typical laser diodes caused by increased

temperature.
