Published : 22 Feb 19
Description
This application report outlines the advantages of using ultra-high performance clock synchronizers from Texas Instruments to generate reference clocks needed for high-speed serial links using 56G PAM-4 signaling and even meets early requirements of 112G PAM-4 links. A methodology for deriving reference clock jitter requirements is described and the advantages of clocking such a system with the
