**Proper operation of the device is guaranteed only within the ranges specified in this section. After

the device has completed power-up, VDDVARIO and the magnetics power supply must maintain their

voltage level with +/-10%. Varying the voltage greater than +/-10% after the device has completed

power-up can cause errors in device operation.

Power Consumption

This section details the power consumption of the device as measured during various modes of

operation. For each mode of operation, two tables are provided: one for operation of VDDVARIO (and

magnetics) at 2.5V, and the other for operation of VDDVARIO (and magnetics) at 3.3V. Power

consumption values are provided for both the device-only, and for the device plus Ethernet

components. Power dissipation is determined by temperature, supply voltage, and external source/sink

requirements.
