Stratix 10 Native PHY Usage

Hi, 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 Nat...

Hi HPB, Are you referring to the support from transceiver data channel pin or refclk pin ? If it's regarding transceiver refclk pin then I can see that Stratix 10 datasheet table 38 and table 49 did mentioned about the support for PCIe refclk pin with spread spectrum modulating clock frequency from 30kHz to 33kHz and Spread spectrum downspread from 0-5%. But we don't have such spec support for transceiver data channel. Thanks. Regards, dlim

    Hi @DeshiL_Intel​ ,

    My concern is on the receiver side (and non-PCIe protocol). If I feed the down spread bit sequence @20Gbps from the external source, whether Stratix 10 CDR can recover the correct data?

    With Regards,
