Default Re: 20.431 Mhz Crystal wanted

Sorry I don't have the exact crystal but here is a list of 20Mhz range that I do have incase anything might be pullable for your application.

20.030, 20.105, 20.250, 20.550, 20.7360 and 20.930Mhz. No idea what the capacitance is for any of these or if series or parallel loading.

David is right about the questions for getting new crystals cut. I tried to get some last year but not knowing all those specifications failed, I even sent a copy of the circuit for their tech guy to try and work it out. I never got any response, so decided to use the vco method for my application.
