Crystal oscillator stability

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. The oscillator frequency is often used to keep track of time, as in quartz wristwatches, … See more Piezoelectricity was discovered by Jacques and Pierre Curie in 1880. Paul Langevin first investigated quartz resonators for use in sonar during … See more Electrical model A quartz crystal can be modeled as an electrical network with low-impedance (series) and high-impedance (parallel) resonance points spaced closely together. Mathematically, using the Laplace transform, … See more Crystals can be manufactured for oscillation over a wide range of frequencies, from a few kilohertz up to several hundred megahertz.

WebThis type of oscillator achieves the highest frequency stability possible with a crystal. They are typically used to control the frequency of radio transmitters , cellular base … 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 than the recommended maximum value, the better the oscillator start up and stability. A common test for oscillator stability is the negative resistance method (see Section 4.2).
