SRIS support in pg239 PCS's elastic buffer

Jump to solution

Hello,

We are using Ultrascale+ FPGAs and would like to check whether elastic buffer in pg239's PCS can support SRIS, i.e. can tolerate 5600ppm differences. If that is true, how should I configure/enable pg239 into SRIS mode? Thanks

btw, I did a quick search, and found only one similar topic below, but the poster was actually using SRNS in my understanding.
