    Hi Kerr,

    You can find this information in datasheets table 3.
    In default operation, the DP130 uses ADDR_EQ to select the equalization, CAD_SNK=L for DP operation, and link training is ON.
    For these conditions:
    ADDR_EQ=Vim -> Fixed EQ 8dB at 2.7GHz(5.4Gbps)
    ADDR_EQ=Vil -> EQ from 0dB to 8dB at 2.7GHz(5.4Gbps), depends on pre-emphasis level
    ADDR_EQ=Vih -> EQ from 6dB to 15dB at 2.7GHz(5.4Gbps), depends on pre-emphasis level

    Regards
