KSZ9031RNX
Typical Current/Power Consumption
Table 12 through Table 15 show the typical current consumption by the core (DVDDL, AVDDL, AVDDL_PLL), transceiver
(AVDDH) and digital I/O (DVDDH) supply pins, and the total typical power for the entire KSZ9031RNX device for various
nominal operating voltage combinations.
