Hi

you could find your answer here, but this frequency is too low for your purpose and also it has some problem (runt events):

Hi,
The highest frequency you can produce with the ESP32 is 80 Mhz.
Internally, there are many frequency options of 160, 240, 560 Mhz or WIFI.
But so far, I find it impossible to drive more than 80 MHz to the outside world.

I2S0 Clock (master clock) up to 80MHz derived from APLL clock
