Cortina Announces Quad 10G EDC Device

Cortina Systems
introduced its CS4317 Electronic Dispersion Compensation (EDC) PHY -- quad 10G device. It integrated MAC layer security, IEEE 1588 v2, and support for 10G SFP+ and IEEE 802.3ba 40G and 100G interfaces. The device is offered in a 17 mm × 17 mm package, which is the smallest in the industry.

The device supports a variety of 10G and 40G (4 × 10G) line-side optical modules, as well as both passive and active copper interconnects. The CS4317 Quad EDC PHY provides Electronic Dispersion Compensation capability on the receive SFI interface that exceeds the requirements of IEEE 802.3aq 10GBase-LRM, SFF8431 linear interface, 10GBase-ZR, and IEEE 802.3ba nPPI specifications.

The device supports 10G/8G/4G/2G/1G FC data rates and Fibre channel rate negotiation. The device also supports the CR4 and CR10 auto negotiation and training as specified by IEEE 802.3ba. The device is fully autonomous and does not require external processors to control the initial convergence or the dynamic adaption of the dispersion compensation. The CS4317 supports both serial XFI and RXAUI host interfaces, and is compliant to the IEEE 802.3ba nAUI specifications.

Sampling is underway.

"The 10G market is ramping, and the 40G and 100G market growth demands support for the IEEE 802.3ba specification," said Scott Feller, product line director at Cortina. "To enable next generation 10G, 40G, and 100G networks from routers to NIC cards to storage boxes, Cortina has integrated features such as MAC Security and IEEE 1588 v2, and support for RXAUI, XFI, and nAUI host interfaces, as well as all line-side optical and copper interface types into the CS4317 device."
