Power Consumption (Device Only)
This section provides typical power consumption values for the LAN9211 in various modes of
operation. These measurements 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.
