According to the ESP32 datasheet, the RTC Controller's ADC can sample at 200ksps and the DIG Controller's ADC can sample at 2 Msps.
With a max latency of 10 microseconds, you won't have a lot of margin to work with, but maybe.

Hello everyone, I need to source a continuous clock between 4MHz and 12 MHz from the ESP32-WROOM-32 module and get it out to one of the pins to drive some external circuitry. Any ideas? The LEDC and other PWM examples can't seem to handle anything that fast. I can generate the clock with the SPI per...
