Hey, I'm new to pcb design and currently ponder about what oscillator to use for my atmega16u2 usb board. I see that most people use a crystal, and this would be the safe way to go.
Can someone explain to me if a simpler (and cheaper) option, which would be a ceramic oscillator, would suffice?
It only needs to follow usb hid protocoll reliably. I also use pwm, but only for led dimming, no matrix or other more precise stuff.
I havn't found anything on ceramic oscillators with atmega usb and would be grateful if someone here can answer this question.
