Hi,
A while back I purchased a 32768 Hz crystal at a local store. Now that I'm going to use it in conjunction with a CD4060 I realize that I need to know the load capacitance. I've asked them for a datasheet and they say they can't provide one. It's a HC49/U type, whatever that means and it looks like this:
If I stick it in a breadboard with 50 pF or other values that I have, what should I be looking for in a crystal that Is running well? I guess I can't scope a crystal directly but maybe I can buffer it with a jFET opamp?
