    Default Caps Around Resonator

    If I use a Resonator that has built in caps, should I still put external 22pf caps around it or none at all?
    Thanks,
    John

    3-pin resonators with built-in caps do not need external caps.

    Yep what Bruce said.
    Also, the center pin is always ground and the other two pins connect to OSC1 and OSC2.

    Heres a link to the catalog page of Digikey.

    We only use Resonators...

    You don't need capacitators and they are cheap ! They are great !

    (Do you really need a precisious timebase ?)
