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.
Copper TP operation is assumed. Current is zero if 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
