Power Consumption (Device and System Components)
This section provides typical power consumption values for a complete Ethernet interface based on
the LAN9220, including the power dissipated by the magnetics and other passive components.
Note: The power measurements list below were taken under the following conditions:
Temperature: ................................................................................................................................... +25°C
Device VDD (VDDVARIO, VDD33REG, VDD33A): ....................................................................... +3.30V
Note: Power dissipation is determined by operating frequency, temperature, and supply voltage, as
well as external source/sink requirements.
