Part Number: DP83822H

Hello,

DP83822H uses RMII interface. The chip can detect the network card, but cannot obtain the IP address. Please help analyze the reasons.
The schematic diagram is shown below. Please help check if there are any issues. Thanks.

    Hi,

    Are you able to link up? I am looking at the schematic, do you have the 49.9ohm termination network to 3.3V on the MDI side?

    Some of strapping resistors are not following the recommended strap resistor ratios as shown below and I would recommend to fix this.

    Thanks
