Power Consumption (Device and System Components)

This section provides typical power consumption values for a complete Ethernet interface based on

the LAN9211, 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:................................................................................................................................... +3.30V

Note: Power dissipation is determined by operating frequency, temperature, and supply voltage, as

well as external source/sink requirements.
