"WebAug 26, 2011 · A crystal oscillator is a timing device that consists of a crystal and an oscillator circuit, providing an output waveform at a specific frequency. When a crystal is placed into an amplifier circuit (as shown in Figure 1), a small amount of energy is fed back to the crystal, which causes it to vibrate. " - Crystal pullability

WebJul 3, 2024 · The pullability of the oscillation system refers to which extent it is possible to tune the resonance frequency of the crystal by changing these values. The crystal sees these capacitors in series through ground, parallel to the closed loop. They will therefore slightly alter the anti-resonance frequency of the crystal. WebThe dependence of frequency on deviation from specified load is called "pullability". It depends on the ratio between motion capacitance and load capacitance, with typical value of 0.1- 0.2ppm ppm per 1pF of load mismatch. Obviously a care needs to be taken of crystal ESR when selecting it, but it would take another "dissertation" to submit.
