DP83869HM: Require detailed current draw specifications for three supply mode

Part Number: DP83869HM

Hi,

Are there specific current draw specifications for all three rails in all modes. The data sheet appears to only show total power.

Thanks,

Mitch

  • Hi Mitch,

    Can you provide the functional mode which you need current break down?

  • I am interested in characterizing currents for following modes:

    RGMII to Copper (1G) (100m cable, 50% utilization)

    RGMII to 1000Base-X (50% utilization)

    1000Base-TX to 1000Base-FX (100m cable, 50% utilization)

  • Hi Mitchell,

    Attached is the current consumption for the modes you requested.

    RGMII to Copper mode (100m cable, 50% utilization)
    Speed VDDIO = 1.8V/3.3V VDD2P5 = 2.5V VDD1P0 = 1.0V VDD1P8 = 1.8V
    V(V) I(mA) Power (mW) I(mA) Power (mW) I(mA) Power (mW) I(mA) Power (mW)
    1000 1.8 17 30.6 88 220 119 119 52 93.6
    1000 3.3 30 99 88 220 120 120 52 93.6
