Thank you very much for your cooperation.
The good news Is that I have just checked and I need a maximum output of 100kHz (per output).
I don't know if 4 independent outputs, generating 100kHz at the same time will have the same problem.
If they have, maybe I'll just have to stick with a maximum ceiling of 25kHz per output (100kHz simultaneous)
Anyway, I'm willing to pay (or retribute in the future, for example) for this to be coded.
Clearly any information seems like gold to me now, so feel free to tell me your thoughts
