Multi-Rate VCSEL Driver
Product Brief
January 2004
Description
The growing use of the Internet and the
increasing demand for storage area network
(SAN) solutions has created the need for next
generation physical layer ICs. In addition the
introduction of 4 G Fiber Channel (4GFC) has
introduced the need for next generation ICs to
be backwards compatible with 1 G and 2 G
Fiber Channel. The Zarlink PX5410 provides
a multi-rate VCSEL driver solution for 1, 2, and
4GFC.
The Zarlink PX5410 Multi-Rate VCSEL Driver
is designed for various applications up to 4.25
Gb/s. 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, SFF-8472 controllers, or
microcontroller DAC outputs. Selectable
temperature compensation and closed-loop
average power control deliver optimized
optical output power and extinction ratio over
temperature.
