I have a system which uses custom interface for communication. The system transmits at 20Gbps with Spread spectrum enabled. Whether I can connect that system to Stratix 10 Transceiver using Native PHY and recover the data properly (Stratix 10 doesn't support Spread spectrum recovery as in data sheet).
Downspread rate ~30KHz , Downspread range is ~0.45%
Hi @DeshiL_Intel ,
Thanks for your viewpoint.
I was doing feasibility study and In my view, if there is a downspread means there will be little variation in the data rate (x ppm) induced due to the downspread. Stratix 10 Receiver tolerates -1000 to +1000 ppm variation in the incoming data as per the Stratix 10 data sheet. If the difference in ppm after downspread out of (-1000 to 1000ppm) range then I doubt the recovery will be false free.
Correct me if my understanding is wrong regarding Transceiver's receiver ppm threshold.
