CS4340
- Octal 10G CDR with Quad EDC
The Cortina Systems® CS4340 Octal 10G CDR PHY with Quad Electronic Dispersion Compensation (CS4340 EDC PHY) is a highly integrated device with eight 10 Gbps clock and data recovery (CDR) circuits. The four receive channels have the optional integrated Electronic Dispersion Compensation (EDC) capability. This functionality supports 4 SFP+ modules that can be either limited or linear, or a single 40G QSFP or CFP module. Enabling the EDC capability allows the device to operate with linear SFP+ optical modules to support 10Gbase-LRM and SFF8431 Direct Attach Copper cables 7 meters and longer.
Like the previous two generations of Cortina™ EDC devices, the CS4340 EDC PHY maximizes datacenter, server, and switching efficiency with its low power, low latency implementation of the PHY functionality. Due to its hybrid DSP analog architecture, the CS4340 EDC PHY has latency of less than 1 ns.
