PX6514
4 x 10 Gb/s VCSEL Driver
Product Brief
April 2006
Features
•
•
•
•
Single +3.3 V supply dissipating 140
mW per channel
4-channel VCSEL driver operates from
DC to 10.7 Gb/s
Serial digital interface for global and
individual channel control
Individual channel control for enable,
modulation current, bias current, and
VCSEL fault control
•
•
Adjustable temperature compensation
for VCSEL bias and modulation current
VCSEL fault detection with autonomous
fault handling and interrupt
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.
•
•
Adjustable VCSEL peaking control
250-micron channel pitch matches
optical ribbon fiber and VCSEL arrays
•
Differential CML compatible inputs
with on-chip termination
Applications
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
•
4-lane 10GbE, 10GFC, 8GFC, 4GFC,
and OC-192 VSR parallel optical
modules
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.
•
•
Proprietary OC-768 parallel optics
and CWDM
Proprietary 4-lane intra-system
parallel optics
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.
