For clarity and asking questions in this regard.
I cut off all signal paths or polarity to the ADC0 input

I enclose my connection proposal.

Thank you very much for help. I am looking for a LAN8720 connection scheme for OSD3358-512-ISM but I can not find one. The only scheme that seems to be useful is attached, but it still does not fully explain. I do not know how to connect ETHRXER (AM335). I do not know how to connect nINT / REFCLK from the LAN8720 module. There is a problem with the 50MHz clock. Can you help us in this matter. The 50MHz generator is on the LAN8720 ETH BOARD, if needed we can use it as a source for the RMII AM335X

Dear Erik,

I have some doubts. Hint, please ask what electric potential has the pin marked in yellow. If it is GND then why has a separate grommet. It can be connected to the central grommet.

Please find attached screen.

Bye
