    Note:
    1. Input must be externally AC-coupled.
    2. VRX_DIFFp-p is also referred to as peak to peak input differential voltage
    3. The concept of this parameter is equivalent to the Electrical Idle Detect Threshold parameter in PCI Express. Refer to
    PCI Express Differential Receiver (RX) Input Specifications section for further explanation.
    4. The LSTS shown in the table refers to the LSTSAB or LSTSEF bit field of MPC8572E’s SerDes 2 Control Register.
    5. VCM_ACp-p is also referred to as peak to peak AC common mode voltage.
    6. On-chip termination to SGND_SRDS2 (xcorevss).
