Part Number: DP83869HM

Hi I would like to know what the power consumption is for the two voltage supply configuration so VDD1P1 and VDD2P5 when the below interface is used

RGMII to copper 10/100/1000 speeds

Many thanks Andy

    Hi Andrew,

    I've provided the power supply current consumption values for RGMII to Copper mode across speeds below:

    Power Supply Rail Operational Mode Typical  Unit
    I(1V1) RGMII to Copper (1G) 131 mA
    I(1V1) RGMII to Copper (100M) 47 mA
    I(1V1) RGMII to Copper (10M) 37 mA
    I(2V5) RGMII to Copper (1G) 86 mA
    I(2V5) RGMII to Copper (100M) 46 mA
    I(2V5) RGMII to Copper (10M) 76 mA
    I(VDDIO=3.3V) RGMII to Copper (1G) 30 mA
    I(VDDIO=3.3V) RGMII to Copper (100M) 13 mA
    I(VDDIO=3.3V) RGMII to Copper (10M) 10 mA
    I(VDDIO=1.8V) RGMII to Copper (1G) 17 mA
    I(VDDIO=1.8V) RGMII to Copper (100M) 6 mA
    I(VDDIO=1.8V) RGMII to Copper (10M) 5 mA

    Regards,
