Multi-Rate VCSEL Driver

Product Brief

September 2004

Description

The growing use of the Internet has created

increasingly higher demand for multi-Gb/s I/O

performance. The demand for 10+ Gb/s WAN

bandwidth fuels the growth of short-reach 10

Gb/s infrastructures within high-end telco and

datacom routers, switches, servers and other

proprietary chassis-to-chassis links.

The Zarlink PX6410 10 Gb/s serial VCSEL driver

is designed for various 10 Gb/s PMD

applications. It consists of a DC-coupled

amplifier with adjustable modulation and bias

currents optimized for driving commercially

available VCSEL-based transmit optical sub

assemblies (TOSAs) from a single +3.3 V supply.

VCSEL modulation and bias currents can be

programmed by a variety of means including

external resistors, programmable potentiometers

or microcontroller DAC outputs. Selectable

current temperature coefficients and APC

feedback control allow optical output power and

extinction ratio to be maintained over

temperature.
