WebHigh stability The crystal has high stability due to the presence of quartz crystal. High operating frequency It is also due to piezoelectric crystals connected in parallel with the resonance circuit. Disadvantages. The disadvantages of crystal oscillator are as follows: The low operating frequency crystals are not readily available. Webcrystal. The oscillator becomes unstable and stops oscillation if the ESR becomes too high. Hence, each oscillator has maximum limits of the ESR value. The lower the ESR …
The frequency stability is determined by the crystal's Q. It is inversely dependent on the frequency, and on the constant that is dependent on the particular cut. Other factors influencing Q are the overtone used, the temperature, the level of driving of the crystal, the quality of the surface finish, the mechanical … See more A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric crystal as a frequency-selective element.
