Cortina’s Octal SFP+ EDC PHY Enables Higher Density Data Center and Enterprise Switches
Sunnyvale, Calif., July 26, 2012 — Cortina Systems, Inc. (Cortina®), delivering innovative technologies that link people and networks worldwide, today announced the CS4342, an octal 10G Electronic Dispersion Compensation (EDC) device, which delivers low latency and standards compliance in the industry’s smallest footprint The CS4342’s 17mm x 17mm package is 34% smaller than other competitive devices available in the market, reducing valuable PCB real estate requirements in today’s high density 10GbE SFP+ and 40G QSFP+ line cards. It reduces latency, a critical parameter in data center and financial applications, to less than a nanosecond, virtually eliminating the contribution of the PHY layer to the overall link latency. The CS4342 incorporates the latest standards and technologies for 10G, 40G, and 100G optics and copper cables, including support for diverse standards such as 10Gbase-LRM, 10G Direct Attach Copper, 10GBase-ZR, and DWDM, which allows equipment manufactures to create one line card to support all standards. The CS4342 joins Cortina’s industry leading portfolio of dual and quad EDC PHYs that are shipping in volume to leading switch system vendors.
“The increasing demand for bandwidth is driving up both data center and enterprise switch densities” said Scott Feller, director at Cortina Systems, Inc. “Cortina worked closely with system developers to create a high performance device that is compliant to multiple industry standards, incorporating high port counts, low power, and the density required for the next generation of switches and routers.”
“With the majority of datacenter interconnect bandwidth for the next few years expected to be handled by 10GbE and 40GbE, high density, small footprint 10GbE and 40GbE solutions are critical to handling the exponential growth in bandwidth intensive consumer applications like uploading photos to Facebook, videos to YouTube and streaming high-definition video. Video is expected to be one of the main bandwidth drivers of the Internet in the near future.” commented Brad Smith, Senior VP at LightCounting, a market research company focusing on optical interconnects. “ Space is at a premium in these high density solutions, whether it is switch faceplate or PCB board area, driving the requirement for higher integration and smaller footprint across all components in the system.”
CS4342—Octal EDC Device:
The CS4342 PHY functionality supports eight full duplex 10G links or two full duplex 40G links. Both transmit and receive paths include Clock and Data Recovery (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. EDC capability allows the device to operate with linear SFP+ optical modules to support 10Gbase-LRM, Direct Attach Copper, and 10GBase-ZR and DWDM SMF applications. The device is fully compliant to 10G SFP+ and 802.3ba 40G and 100G nPPI and nAUI specifications. The transmit path includes a 10Gbase-KR compliant 3 tap transmit pre-emphasis capability. The transmit pre-emphasis in conjunction with the receive EDC enables the device to support 10Gbase-KR, 8G FC, and telecom backplane applications. The device is fully autonomous and does not require external processors to control the initial convergence or the dynamic adaption of the dispersion compensation. In addition, the device includes extensive debug features and I/Os for device monitoring and control.
