DC Characteristics for VDDIOMAC or VDDIOMICRO at 2.5 V
Current Consumption
The current consumption values listed in this section are based on nominal values and
the PHY operating with full-duplex enabled and a 64-bit random data pattern at 100%
utilization. Values are grouped by the type of link and whether the on-chip switching
regulator is enabled.
Consumption with 1000BASE-T Link
The following table shows the current consumption values with a 1000BASE-T link and
the on-chip switching regulator enabled.
Current Consumption: 1000BASE-T, Regulator Enabled
