Note 6: VDD12TX1, VDD12TX2, OSCVDD12, VDDCR
Note 7: Current measurements do not include power applied to the magnetics or the optional external LEDs.
Note 8: The Ethernet component current is independent of the supply rail voltage (2.5V or 3.3V) of the transformer.
Two internal PHY copper TP operation is assumed. Current is half if only one PHY is enabled or if one PHY
is using 100BASE-FX mode. Current is zero if neither PHY is enabled or if both PHYs are using 100BASE-
FX mode.
Note 9: This includes the power dissipated by the transmitter by way of the current through the transformer.
Note 10: 3.3*(A) + 1.2*(B) + (2.5)*(C) @ Typ
Note 11: 3.3*(A) + 1.2*(B) + (3.3)*(C) @ Typ
