On our P4080 design we have DC coupling on the SGMII receiver. It is driven by a CML output stage power by 1.4Volts. The XVDD voltage on our design is 1.5 Volts. Table 88 does not specify a DC Input voltage range. Do you happen to have a value for this? Do you think this will be a issue since the driver is at 1.4 Volts?
Table 88 does not specify a DC input voltage range because it says "Input must be externally AC coupled." I think you should change to AC coupling, otherwise you violate P4080 electrical specifications requirement.
