DP83TG720R-Q1: VDD OV/UV protection

Part Number: DP83TG720R-Q1

Hi Expert,

Is there have OV & UV protection for VDDIO/VDDA1P3/VDDA1P0? I can not find this from the datasheet. But I found below register which have the under volt and over volt interrupt status.

  • What is the threshold for OV & UV?
  • If the OV or UV happen, what is the status for DP83TG720R-Q1? Does it have some protection? For example, does it will enter the standby mode after OV/UV detected?

 Thanks!

    Hi Ethan,

    It is strongly recommended that PHY supplies be kept within their recommended operating conditions as noted in section 7.3. Any deviation from these voltages is a risk taken by customer and may lead to non-intended performance.

    Sincerely,

    Gerome
