Cortina Unveils Smallest Quad 10G Electronic Dispersion Compensation Device

By Shamila Janakiraman, TMCnet Contributor

Cortina Systems (News - Alert), Inc. providing innovative technologies for linking people and networks across the globe announced the introduction of CS4340, presumably the smallest quad 10G Electronic Dispersion Compensation or EDC device.
According to company sources the Cortina CS4340 is a programmable 4-port SFP+ PHY with integrated EDC and is available in a small 15 mm x 15 mm BGA package that optimizes system design options. Its density and performance enables 48-port 10G or 12-port 40G line cards which support both optical and copper links and are compliant with industry standards.
The new device is similar to the previous two generations of Cortina EDC devices as it also maximizes datacenter, server, and switching efficiency with its low power, low latency implementation of the PHY functionality. The hybrid DSP analog architecture features latency of less than 1 nsec.
The CS4340 PHY’s versatile design and performance also ensures full compliance to industry standards. These features allow it to be used in either a standalone operation or programmed to optimize application specific performance and power.
The interoperability feature has been proven at industry plugfest, such as Ethernet Alliance’s (News - Alert) SFP+ Direct Attach Copper interoperability tests performed at UNH-IOL. The CS4340 PHY increases application margins and link distances, confirmed company sources.
Scott Feller, product line director at Cortina said, “EDC enabled 10G and 40G links are now a reality; system architects need standard compliant devices that can be deployed in datacenter switches, core routers, and KR Backplanes.”
“With our proven industry leading solution, standards compliance, and small form factor, the CS4340 PHY meets these needs and enables a single system design that addresses the complete spectrum of applications,” Feller added.
The CS4340 PHY functionality supports four full duplex 10G links. Also both transmit and receive paths include Clock and Data Recovery or CDR circuits. The device has a wide operating frequency range covering 1GbE, 1G FC, 2G FC, 4G FC, 8G FC, SONET (9.5 – 11.3G), and 10GbE. Again the EDC capability enables the device to operate with linear SFP+ optical modules for supporting 10Gbase-LRM and Direct Attach Copper.
Cortina Systems innovates continuously in advanced port processing and intelligent port connectivity to enhance its offerings. The company provides intelligent communication solutions for the core, metro, access, digital home, and enterprise network market segments. It provides high-speed, analog-digital integration technology solutions which enable faster time-to-market, longer time-in-market, and increased revenue opportunities.
