#93697 - Quartz crystals
Responding to: ???'s previous message
Do you mean these quartzes?

They seem to be pretty good. Choose a HC-49/U package, these types show the lowest dampening.

Yes Kai, but I am using the HC-49/S type. I am also following the datasheet for the micro and using 33pf caps as well.

Thanks for all the info.
