Cortina: Industry's smallest footprint, quad 10G EDC PHY chip

Cortina Systems has announced the CS4317 Electronic Dispersion Compensation (EDC) PHY chip. Cortina says this device is the industry's most integrated, smallest footprint quad 10G EDC device. CS4317 packs MAC layer security and IEEE 1588 v2, and support for 10G SFP+ and IEEE 802.3ba 40G and 100G interfaces in a 17 mm × 17 mm package. By using CS4317 system designers can design systems to enable deployment of 10G, 40G, and 100G links supporting the latest security and synchronization features and interconnect capabilities.

"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."

"In addition to support for SFP+ and QSFP+ interface types, the CS4317 includes an integrated 2×2 crosspoint switch, an extensive set of digital I/Os that can be used to control and monitor the SFP+ modules, and LED drivers, enabling the offload of functionality from the silicon real estate and I/O strapped ASICs in today's high density 10 and 40 GbE and 1 platforms."

The Cortina Systems CS4317 Quad EDC PHY with MAC Security is a low power, 10 Gbps PHY device with IEEE 1588 Precision Timing Protocol functionalities. This device supports a variety of 10G and 40G (4 × 10G) line-side optical modules and both passive and active copper interconnects. Cortina claims 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.

The CS4317 has an integrated 2×2 switch enabling protection switching applications and support for line card designs with both SFP+ and QSFP+ interfaces, with the ability to dynamically switch between the two based on field requirements.

The CS4317 includes 28 GPIO and 4 independent I2C interfaces that can be configured to monitor and control the SFP+ modules connected to the device. It also has 8 programmable LED pins capable of driving single color or bi-color LEDs. The device includes extensive test and debug capabilities including line and host side loopback, PRBS generators and checkers, and full eye scan capability for the transmit and receive 10G paths.
