UX 2210

155Mbps to 2Gbps Laser Driver

Features

General Description

+3.0V to +5.5V Supply Voltage

Automatic Power Control .

Temperature-Compensated Modulation

Current

The UX2210 is a complete CMOS laser driver for

155Mbps to 2Gbps.It consists of a bias current

generator with automatic power control (APC), a

modulation current driver and a reference

Programmable slow start

voltage

generator

with

temperature

Rise and Fall Times less than 250ps

Apply to FP、DFB、VCSEL Laser

compensation. The UX2210 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.
