Note 6-1
Current consumption is for the single 3.3V supply KSZ8041NL/RNL device only, and includes the
1.8V supply voltage (VDDPLL_1.8) that is provided by the KSZ8041NL/RNL. The PHY port’s
transformer consumes an additional 45 mA @ 3.3V for 100BASE-TX and 70 mA @ 3.3V for
10BASE-T.
Note 6-2
TA = 25°C. Specification for packaged product only.
