Hello
We have two DP83867IS on our product. I used 3-supply configuration and VDDIO = 3.3V. Picture below shows the connection of power pins. Power up sequence is 3.3V -> 2.5V -> 1.8V -> 1.0V. Datasheet says power sequence is required just for 2.5V and 1.8V, it is fulfilled. But I can see a current leakage from 3.3V (VDDIO) to 1.0V rail during power up, see picture below. 1.0V rail is connected to DP83867IS chips only, so I believe leakage current goes through the PHY chips. Can you please let me know if it is normal behavior for DP83867IS and do you think it can be a potential issue for us (a possible malfunction or damage in a time)? Thank you
Best regards
Libor
