DD
should have no more than 40 mVpp AC power supply noise superimposed on the high power supply voltage for the
PHY core (1.8 V nominal DC value). At the same time, VDD should have no more than 20 mVpp AC power supply noise
superimposed on the low power supply voltage for the PHY core (1.0 V nominal value or 1.1 V overdrive DC value).
The power supply voltage variation for the PHY core should have less than +/-5% including the board-level power supply variation
and on-chip power supply variation due to the finite impedances in the package.
