Use RMII in ESP32-WROOM-32U

Postby alpesh_borad » Sat Sep 15, 2018 8:34 am

Hello,

I am using RMII mode in ESP32-WROOM-32U using KSZ8041RNL.
According to KSZ8041RNL datasheet, it will give 50MHz clock output which will given to MAC (ESP32-WROOM-32U).
So here how i will connect to MAC (Pin#)?

Regards,
Alpesh.

Hello,

Thank you very much for the Answer.

What is the value of Pull up resistor on GPIO0 using as EMAC_TX_CLK.

Have you any reference schematic?

Please provide if you have.
