Cortina intros quad 10G EDC with 1588v2 support

Cortina Systems, Inc. says its new CS4317E electronic dispersion compensation (EDC) PHY with IEEE 1588v2 support is the industry’s first quad-10G EDC device targeted at non-temperature controlled environments encountered in outdoor and industrial deployments.

The new chip integrates IEEE 1588 Precision Timing Protocol (PTP) and MACSec security features. The support for industrial temperature operation and integration of IEEE 1588v2 capability makes the CS4317E EDC PHY an ideal candidate for Ethernet backhaul links, which use 1588 for timing synchronization between network nodes, the company claims.

“Service providers are continuously looking for ways to cut cost while maintaining high service reliability,” said Scott Feller, product line director at Cortina. “Unlike data center applications where the temperatures are well controlled, cellular and industrial-grade applications require operation in extreme temperature environments. With an operating temperature range of -40°C to +85°C, the CS4317E enables these applications by extending the cost advantages of 10GbE to new markets.”

The Cortina Systems CS4317E Industrial Temperature Quad EDC PHY with IEEE 1588v2 is a low-power, 10 Gbps PHY device with MACsec security and IEEE 1588v2 support. This device is compatible with a variety of 10G and 40G (4×10G) line-side optical modules, as well as both passive and active copper interconnects.

The CS4317E provides electronic dispersion compensation capability on the receive SFI interface that meets the requirements of SFF8431 linear interface, 10GBase-ZR, and IEEE 802.3ba nPPI specifications. It also supports 10G/8G/4G/2G/1G Fibre Channel data rates and rate negotiation. For CR4 and CR10 direct attach cables, the auto negotiation and training specified by IEEE 802.3ba is supported. 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 CS4317E supports both serial XFI and RXAUI host interfaces, and is compliant to the IEEE 802.3ba nAUI specifications.

The device is now sampling.
