I spoke with Jim Simmons at Microchip about using a 20MHz resonator on a PIC
(16C621), and he told me that many people were not able to make this work,
but he had spoken with one customer that hadn't had any trouble with his
particular brand; unfortunatly Jim could not remember what brand it was that
worked.  Has anyone discovered a working, reliable 20MHz resonator solution?

Also, anyone have any thoughts on whether or not a 20MHz resonator would be
good for reliable 9600 Baud serial communication?

Thanks,
