Description
The growing use of the Internet has created
increasingly higher demand for multi-Gb/s I/O
performance. The demand for 100 Gb/s+ WAN
bandwidth fuels the growth of short-reach 40
Gb/s infrastructures within high-end telco and
datacom routers, switches, servers and other
proprietary chassis-to-chassis links.
The Zarlink PX6514 4x10 Gb/s VCSEL Driver is a
four-channel VCSEL driver designed for various
4x10 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 Primarion PX6514 VCSEL
driver settings is loaded by a simple four-wire
CMOS compatible serial interface that features
read/write and daisy chain capabilities.
