    Hi,

    ​

    I understand, your confusion. My understanding is that from the statement i.e., "The transceivers do not support the XGMII interface to the MAC/RS as defined in the IEEE 802.3-2008 specification. Instead, they support a 64-bit data and 8-bit control SDR interface between the MAC/RS and the PCS." it is Single Data Rate Only but width of data and control word becomes double i.e., 64-bit and 8-bit Actually you achieves the same data rate.


    So, no need to sample at rising and falling edge for double data rate.


    Hope this clarifies.


    Thank you,

    Kshitij Goel
