SGMII AC Timing Specifications
This section describes the SGMII transmit and receive AC timing specifications. Transmitter and receiver
characteristics are measured at the transmitter outputs (SD2_TX[n] and SD2_TX[n]) or at the receiver
inputs (SD2_RX[n] and SD2_RX[n]) as depicted in Figure 10, respectively.

Notes:
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
4. The LSTS shown in this table refers to the LSTSCD bit field of MPC8544E SerDes 2 control register 1.
5. VCM_ACp-p is also referred to as peak-to-peak AC common mode voltage.
