Quad Port 8.5 Gbps to 11.3 Gbps CDR with EDC

The VSC8247 is a quad channel clock and data recovery (CDR) receiver with on-chip adaptive electronic

dispersion compensation (EDC), programmable input equalization, and selectable pre-emphasis

output. Operating at 8.5 Gbps to 11.3G, the VSC8247 is a versatile CDR and retimer for all 10G Ethernet

and SONET applications. VSC8247 also supports 8G Fibre Channel and 10G QDR Infiniband protocols

and data rates, and all legacy rates. The VSC8247's flexibility makes it an excellent candidate for

upcoming 4x10G and 10x10G CFP modules and high-density photonic integrated circuit (PIC) designs.

Integrated EDC compensates for signal degradations in both the optical and electrical domains. For

optical systems, this includes chromatic dispersion in long-haul single mode fiber systems, and modal dispersion in multimode fiber

systems. High-performance FFE-DFE EDC technology compensates for fiber signal impairment and PCB-related signal degradation.

Feedback from an FEC device can be used for further optimization and enhanced performance. Each channel includes an independent

VScope input signal monitoring integrated circuit and built-in error detector to facilitate product design, production, and deployment.
