12x10 Gb/s VCSEL Driver
Product Brief
January 2005
Description
The growing use of the Internet has created
increasingly higher demand for multi-Gb/s I/O
performance. The demand for 1 Tb/s+ WAN
bandwidth fuels the growth of short-reach 120
Gb/s infrastructures within high-end telco and
datacom routers, switches, servers and other
proprietary chassis-to-chassis links.
The Zarlink PX6419 12X10 Gb/s VCSEL Driver*
is a 12-channel VCSEL driver designed for
various 12x10 Gb/s, 120 Gb/s parallel optics and
CWDM PMD applications. It consists of a DC-
coupled amplifier with selectable modulation and
bias currents optimized for driving commercially
available, common cathode VCSELs from a
single +3.3 V supply.
Individual channel settings are used to control the
modulation and bias current and their
temperature coefficients, allowing the optical
output power and extinction ratio to be optimized.
Data controlling the Zarlink PX6419 VCSEL
Driver settings is loaded by a simple four-wire
CMOS serial interface that features read/write
and daisy chain capabilities.
