Power Consumption (Device and System Components)
This section provides typical power consumption values for a complete Ethernet interface based on
the LAN9218i, including the power dissipated by the magnetics and other passive components. All of
these values are preliminary.
Please refer to the SMSC application note AN14.10 - “Migrating from LAN9118 to the LAN9218I”, that
can be found on SMSC’s web site www.smsc.com, which contains additional details on magnetics and
other components used.
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.
