Hello,

I have a question about software reset of DP83822IF.
How long does PHY Software Reset take from writing a 1 to cleared to 0 automatically.


Best Regards,
itabi

    Hello Itabi,

    I do not have any characterized data for this reset functionality, but I would expect it to be around or under 2 ms.

    I would direct you to "7.7 Timing Requirements, Reset Timing". The timing here is meant for a hardware reset or setting bit 15 of register 0x001f.

    In the reset you are referring to the strap voltages do not get re-sampled.

    Thanks,

    Vibhu
