Cortina Systems, Inc. has released the CS4317 Electronic Dispersion Compensation (EDC) PHY, which it describes as “the industry’s most integrated, smallest footprint quad 10G EDC device.”

Cortina Systems, Inc. has released the CS4317 Electronic Dispersion Compensation (EDC) PHY, which it describes as “the industry’s most integrated, smallest footprint quad 10G EDC device.”

The company highlighted severa features of the 17x17-mm CS4317, including:

  • MAC layer security
  • IEEE 1588 v2 support
  • support for 10G SFP+ and IEEE 802.3ba 40G and 100G interfaces
  • integrated 2x2 crosspoint switch

“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.”

The CS4317 also offers a set of digital I/Os that can be used to control and monitor the SFP+ modules and LED drivers.

The CS4317 supplies EDC 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, Cortina says. 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 Cortina CS4317 is sampling now and will be demonstrated at the upcoming OFC/NFOEC conference. Pricing is available upon request.
