Crystal pullability
WebPullability When a crystal is operating at parallel resonance, it looks inductive in the circuit. As the reactance changes, the frequency changes correspondingly, thus changing the … 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.

Webcrystal ( crystal pullability) and careful selection for value of the frequency setting capacitor (C) is required tradeoff between startup time and frequency shift capability (due to inherent nature of crystal resonators) unwanted but low energy transients may appear in spectrum due to capacitor switching 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.
