Ahh, NCSU my old alma mater. I would recommend Digikey part number X909-ND. That's a 20MHz ceramic resonator with built in capacitance. They are quite rugged, with strong pins that fit easily into sockets. You'll have to put it in sideways of course because of the grounding pin. That's how we did our project for Sutton's class. I assume that's what this is for? ;) Incidentally, you are aware there is a part's shop on campus where you can get most of this stuff for free right? Assuming it is for a class. Reply to me via email if you would like details.

I want to use a PIC16F84A using a 20MHz oscillator. The oscillator needs to be pretty accurate so I think I will need a crystal. Do you have any recommendations what kind/manufacturer/ect that I should use. Part numbers would help me out a lot. Thanks. -------------------------------------------- Joshua Melbourne White Vice Chair NCSU Student Chapter of IEEE Treasurer Eta Kappa Nu, Beta Eta Chapter North Carolina State University Electrical and Computer Engineering -------------------------------------------- -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
