How is that substantially easier than a crystal and two caps or a single ceramic resonator with internal caps? Those canned oscillators are bulky, expensive, use a lot of power, and glitch the supply. At the minimum you need two parts, the oscillator and the bypass cap. About the only advantages are that is uses one less PIC pin and some oscillators can be more accurate than just a crystal. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
