Customer use RMII master mode, they want to have 50MHz for CPU. I noticed that RX_CLK, TX_CLK, CLK_OUT can provide 50-MHz , Could you please help check which one is better to use ? Thanks.

HI Huang,
RX_CLK and TX_CLK are not required in RMII interface. All the pins could generate 50MHz. We recommend connect RX_CLK or TX_CLK to SoC when the PHY is in RMII Master mode.
