- just wondering if there are any huge benefits of using a crystal over a resonator & cap combo?
to my knowledge, you can use either:
-a crystal and TWO capacitors;
-a resonator which is a crystal and capacitors combined in a single 3 lead package;
-the internal oscillator with no external components.
The resonator has an accuracy/stability advantage over the internal oscillator at the cost of one more component, the crystal/caps are the same as the resonator but with still more parts.
