I am trying to find a place where I can order a few resonators at 40 MHz. I would prefer a 3-pin throughole style. I can find manufactures and datasheets, but I can't find the parts at any source that will supply in low quanitities (Mouser, Newark, Digikey, etc.).

A couple questions...

I have a 20 MHz resonator already, is there a way to "divide" that signal to provide my 40 MHz clock?

How would I use a crystal in place of my resonator - is there more hardware involved? They only have two pins, so what happens to the third?

Anyone have a source for 3-pin 40 MHz ceramic resonators?

TIA!
