SGMII DC Electrical Characteristics
Table 26 and Table 27 describe the SGMII DC electrical characteristics. Transmitter DC characteristics are
measured at the transmitter outputs (L1_SD1_TXn and L1_SD1_TXn) as depicted in Figure 8.
NOTE
The voltage levels of the transmitter and the receiver depend on the SerDes
control registers which should be programmed at the recommended values
for SGMII protocol (L1_nVDD =1.0 V).
