Table 4.1 Operational Current Consumption & Power Dissipation (VDD33IO = VDD33A = 3.3V)
Power Consumption
This section details the power consumption of the device as measured during various modes of
operation. Power dissipation is determined by temperature, supply voltage, and external source/sink
requirements.
Operational Current Consumption & Power Dissipation
Note: All values measured with maximum simultaneous traffic on the Ethernet port and all USB ports.
Note: Magnetic power consumption:
100BASE-TX: ~42mA
10BASE-T: ~104mA
