Product Brief

Description
The growing use of the Internet has created
increasingly higher demand for multi-Gb/s I/O
performance. The demand for 40+ 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 PX5514 4x4 Gb/s VCSEL Driver is a
four-channel VCSEL driver designed for various
4x4 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 PX5514 VCSEL driver
settings is loaded by a simple four-wire CMOS
compatible serial interface that features
read/write and daisy chain capabilities.
