PX6410
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.
