Note 5.4
Note 5.5
**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.
Note: Thermal parameters are measured or estimated for devices in a multi-layer 2S2P PCB per
Operating Conditions**
