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.
In terms of the capacitor values I can use the guide to figure that out.
Thank you in advance,
