8.3.2
AC Requirements for SGMII SD_REF_CLK and SD_REF_CLK
This table lists the SGMII SerDes reference clock AC requirements. Note that SD_REF_CLK and
SD_REF_CLK are not intended to be used with, and should not be clocked by, a spread spectrum clock
source.
8.3.3
SGMII Transmitter and Receiver DC Electrical Characteristics
Table 32 and Table 33 describe the SGMII SerDes transmitter and receiver AC-coupled DC electrical
characteristics. Transmitter DC characteristics are measured at the transmitter outputs (SD_TX[n] and
SD_TX[n]) as depicted in Figure 16.

Notes:
1. This will not align to DC-coupled SGMII. XCOREVDD-Typ = 1.0 V.
2. |VOD| = |VTXn – VTXn|. |VOD| is also referred as output differential peak voltage. VTX-DIFFp-p = 2*|VOD|.
3. The |VOD| value shown in the Typ column is based on the condition of XCOREVDD-Typ = 1.0 V, no common mode offset
variation (VOS = 500 mV), SerDes transmitter is terminated with 100- differential load between TX[n] and TX[n].
4. VOS is also referred to as output common mode voltage.
