DC Electrical Specifications
Table 7.3 below lists the worst case current consumption for each of the supplies of the LAN9217.
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°C to +70°C
Device VDD:....................................................................................................................+3.30 V +/- 10%
