    High-Speed Serial Interfaces (HSSI)
    between 100 mV and 400 mV. Figure 40 shows the SerDes reference clock input requirement
    for DC-coupled connection scheme.
    — For external AC-coupled connection, there is no common mode voltage requirement for the
    clock driver. Since the external AC-coupling capacitor blocks the DC level, the clock driver
    and the SerDes reference clock receiver operate in different command mode voltages. The
    SerDes reference clock receiver in this connection scheme has its common mode voltage set to
    XCOREVSS. Each signal wire of the differential inputs is allowed to swing below and above
    the common mode voltage (XCOREVSS). Figure 41 shows the SerDes reference clock input
    requirement for AC-coupled connection scheme.
    Single-ended Mode
    — The reference clock can also be single-ended. The SD_REF_CLK input amplitude
    (single-ended swing) must be between 400mV and 800mV peak-peak (from Vmin to Vmax)
    with SD_REF_CLK either left unconnected or tied to ground.
    — The SD_REF_CLK input average voltage must be between 200 and 400 mV. Figure 42 shows
    the SerDes reference clock input requirement for single-ended signaling mode.
    — To meet the input amplitude requirement, the reference clock inputs might need to be DC or
    AC-coupled externally. For the best noise performance, the reference of the clock could be DC
    or AC-coupled into the unused phase (SD_REF_CLK) through the same source impedance as
    the clock input (SD_REF_CLK) in use.
