Hi Evgeny,

Please refer to section 8.4.1.3 of the datasheet for information on RGMII mode. Figure 8-7 describes how to connect the DP83822HF to the MAC.

Thanks,

David

Hi Evgeny,

Yes, this is correct. Ensure pin 28 is configured with mode 2 or 3 bootstrapping to enable RGMII mode. Also ensure pin 26 is placed in mode 1 to set the 25Mhz reference clock.

Thanks,

David
