Power Consumption (Device and System Components)
This section provides typical power consumption values for a complete Ethernet interface based on
the LAN9215, including the power dissipated by the magnetics and other passive components.
Please refer to the SMSC application note AN14.9 - “Migrating from LAN9115 to the LAN9215”, 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.
