Hello I would like to know what are the frequencies (and its max divisor) i can use with the general purpose clocks pin on the raspberry pi 3B+/4. currently my circuit is using this as a Clock input. I would like to remove that component and just instead use onboard one.
I plan to have 3 clock: 8.1920MHZ, 4.0960MHZ, 2.048MHZ. on the 3 GPIO CLCK. of course it wouldnt be exactly that but i hope to get somewhere close to it.
How clean are its signal? I found this image that at 12Mhz its starting to look sinusoidal is it true?
