VSC8247YJB-01

Application Specific Clock/Timing Overview

The VSC8247YJB-01 is a quad-channel clock and data recovery (CDR) receiver integrated with adaptive electronic dispersion compensation (EDC). Operating within an 8.5 Gbps to 11.3 Gbps range, it supports 10G Ethernet, SONET, 8G Fibre Channel, and 10G QDR Infiniband protocols. The device features high-performance FFE-DFE EDC for optical and electrical signal degradation compensation, independent per-channel operation, and built-in error detection. It utilizes 1.8 V and 1.2 V core power supplies and is housed in a 144-pin FCBGA package.
