Revision 1.6
Electrical Characteristics
Current consumption is for the single 3.3V supply device only, and includes the 1.8V supply voltages (VDDA, VDDC) that are provided via
power output Pin 56(VDDCO). Each PHY port’s transformer consumes an additional 45mA @ 3.3V for 100BASE-TX and 70mA @ 3.3V
for 10BASE-T at fully traffic.
