Note 12: VDD33TXRX1, VDD33TXRX2, VDD33BIAS, VDD33, VDDIO
Note 13: VDD12TX1 and VDD12TX2, are driven by the internal regulator via the PCB. The current is accounted for
via VDD33.
Note 14: Current measurements do not include power applied to the magnetics or the optional external LEDs.
Note 15: 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 16: This includes the power dissipated by the transmitter by way of the current through the transformer.
Note 17: 3.3*(A) + (2.5)*(C) @ Typ
Note 18: 3.3*(A) + (3.3)*(C) @ Typ
