STM64(OC-192) implementation with kintex-7 transceivers using SFP+ without CDR

Hi all,

I received a note from Xilinx that if we want to implement STM64 (OC-192) with Kintex-7 transceivers using SFP+ to meet the STM64 jitter standard we should use SFP+ with CDR. But i ask this problem from producers and they answered me that STM64 jitter standard met by kintex7 and SFP+ wo CDR ( wo retimed).

I think the CDR of kintex -7 if enough.

please help me if I should pay more for CDR.

Bests

Jack
