6.0 ELECTRICAL CHARACTERISTICS
T
A
= 25°C. Specification is for packaged product only. Current consumption is for the single 3.3V supply device only and
includes the 1.8V supply voltages (V
DDA
, V
DDC
) that are provided via power output pin 42 (V
DDCO
).
Each PHY port’s transformer consumes an additional 45 mA at 3.3V for 100BASE-TX and 70 mA at 3.3V for 10BASE-
T at full traffic.
