Many Microchip customers ask us for help when designing their oscillator circuits. Due to the great number of combinations of VDD and temperature ranges, crystal or resonator, loading capacitors, circuit layout and circuit board materials, it is not practical to provide a cookbook process that would work well for everyone or even for most users. However, there are measures that can be used to develop and test for good working oscillator circuits.

This application note breaks down the oscillator design process into the following three parts: specifying the operating conditions, selecting the components and testing oscillator performance. Other concerns are also discussed that may be helpful during layout and testing.
