Cortina Systems® CS4217 Dual 10 Gbps CDR with EDC
Overview
The Cortina Systems® CS4217 Electronic Dispersion
Compensation Device (CS4217 EDC) is a highly
integrated dual port 10 Gbps clock and data recovery
(CDR) circuit. The receive path has integrated EDC to
allow optical modules to extend the operating range of
62.5 μm and 50 μm multimode fiber to 220 m and
beyond. The device integration and low power design
techniques allow XFP 10GBASE-LRM modules to be
built under 1.5 W.
Enabling X2 and XFP Optical Modules
10 GbE port shipments are anticipated to top the
one million mark in 2009, according to the latest
edition of Light Reading’s Components Insider.
The CS4217 EDC incorporates two bi-directional
10 Gbps paths to support the increased port
densities. Additional features of the CS4217 EDC
include various lookbacks, a complete set of
programmable Rx and Tx path functionality, such as
output pre-emphasis, and full 1 GbE data rate
support. Packaged in a small 12 mm by 12 mm flipchip CSP package, the CS4217 EDC has an
integrated microcontroller to enable auto adapation
of dispersed optical signals.
Successful interoperability testing of the CS4217
EDC with SFP+ optical modules from leading vendors
has provided the broadest collection of real life
system application data available in the industry
with coverage for all three applications: SR, LR, and
LRM.
