I am currently building an audio guitar pedal. I was suggested to use an external clock as reference for my CODEC and MCU.
I've been reading the "Oscillator design guide for STM8AF/AL/S, STM32 MCUs and MPUs" application note for a while now. I am trying to understand which oscillator best fits my MCU, however, I am not able to find a good external clock that matches the requirements they pose in the guide.
I am mostly looking for a HSE of about 25 MHz, since I am working with audio.
I would appreciate it if I could get some recommendations for external clocks that would work for my project.
The capacitor values I can figure out using the guide.
