**Proper operation of the device is guaranteed only within the ranges specified in this section. After
the device has completed power-up, VDDIO 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.
Note: Do not drive input signals without power supplied to the device.
This section details the device power measurements taken over various operating conditions. Unless
otherwise noted, all measurements were taken with power supplies at nominal values (VDDIO, VDD1A,
VDD2A = 3.3V, VDDCR = 1.2V). See
description of the power down modes. For more information on the REF_CLK modes, see
