  • [FAQ] DP83822HF: How does power up sequence affect PHY operation?

    Gerome Cacho
    Gerome Cacho
    Part Number: DP83822HF Tool/software: For DP83822, there is a guidance where AVD and VDDIO must not exceed 0.3V prior to complete supply ramp, with an additional footnote suggesting AVD to ramp up after VDDIO to avoid false detection of VDDIO. False detection…
