“Going digital” and “programmable architectures” are the product strategies of today. However no digital system will run without a clock oscillator circuit and “oscillation” is and old and very analogue phenomena that may still need additional clarification. Quite some theory and some practice on this subject based on microcontrollers is covered in this application note. Basically this application note is an addition to AN96103 “Xtal oscillators on 8-bit microcontrollers” It handles with harmonic Xtal resonation and ceramic resonators. Oscillator theory, component value calculations, parameter measurements is one part of this application note, application info with component type numbers is another part.
