Hi HPB, Sorry and understood your concern but as I explained earlier, if this is regarding transceiver data channel then I afraid it's not under Intel supported protocol and hence there won't be any test coverage to tell whether it will works or not. As it's not supported protocol, we can only advise customer to test and verify by themself. Regards, dlim

    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.

    With Regards,

    HPB
