These figures are provided to assist system designers properly design the power supply; they cannot
be used to determine typical power consumption of the device.
Note: The current measurements listed below were taken under the following conditions:
Temperature: ........................................................................................................................0
Device VDD:.................................................................................................................. +3.30 V +/- 10%
Note: Current consumption is determined by operating frequency, temperature, and supply voltage,

as well as external source/sink requirements.
below lists the worst case current consumption for each of the supplies of the LAN9217.
Above figures do not include the supply current for the magnetics. Based on the
recommended implementation, the maximum supply current needed for the magnetics is
108mA.
