Dear Team,

I have an ethernet MAC TO MAC connection between SAMA5D27 and S32K148.

Schematic is attached here.

May I know your comments.

Hi,

for RMII MAC-to-MAC below connection should be done

So the one you have seems to be fine, only:
- S32K148 RMII_TX_CLK is the input
- if RX_ER not used should be tied low

BR, Petr

Thank you.

RX_ER of the both IC's should be connected to GND.

Please correct me if I am wrong
