SGMII Transmitter and Receiver DC Electrical Characteristics
The following tables describe the SGMII SerDes transmitter and receiver AC-Coupled DC electrical characteristics.
Transmitter DC characteristics are measured at the transmitter outputs (SD2_TX[n] and SD2_TX[n]) as depicted in Figure 30.

Notes:
1. This will not align to DC-coupled SGMII. X2VDD-Typ=1.0V.
2. |VOD| = |VSD2_TXn - VSD2_TXn|. |VOD| is also referred as output differential peak voltage. VTX-DIFFp-p = 2*|VOD|.
3. The |VOD| value shown in the table assumes the following transmit equalization setting in the XMITEQAB (for SerDes 2 lanes
A & B) or XMITEQEF (for SerDes 2 lanes E & E) bit field of the chip’s SerDes 2 control register:
The MSbit (bit 0) of the above bit field is set to zero (selecting the full VDD-DIFF-p-p amplitude - power up default);
The LSbits (bit [1:3]) of the above bit field is set based on the equalization setting shown in table.
4. VOS is also referred to as output common mode voltage.
5.The |VOD| value shown in the Typ column is based on the condition of X2VDD-Typ=1.0V, no common mode offset variation
(VOS =550mV), SerDes2 transmitter is terminated with 100-
Ω differential load between SD2_TX[n] and SD2_TX[n].
