DC-Level Requirements for SGMII Configurations
Note:
Specifications are valid at the recommended operating conditions listed in Table 3
Table 15 describes the SGMII SerDes transmitter AC-coupled DC electrical characteristics. Transmitter DC characteristics are
measured at the transmitter outputs (SR[1–2]_TX[n] and SR[1–2]_TX[n]) as shown in Figure 10.

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 the PCI Express interface.
Refer to the PCI Express Differential Receiver (RX) Input Specifications section of the PCI Express Specification document. for
details.
4.
The LSTS shown in the table refers to the LSTSAB or LSTSEF bit fields of the SerDes Control Register.
5.
The supply voltage is 1.0 V.
