WebFrequency stability refers to the allowable deviation from nominal crystal frequency over a specified temperature range. This deviation is measured from the nominal frequency at 25 C. ... the oscillation frequency of the crystal will decrease. The oscillator of the USB device may have difficulty driving a large load capacitance, avoid crystals ... WebJan 6, 2024 · Anyone designing a crystal oscillator will usually have “frequency stability” close to the top of their list of requirements. Hence, all the components used in the circuit (not just the crystal) must be considered with respect to the impact they may have.
WebFeb 9, 2024 · The crystal in combination with the circuit on the microcontroller forms a crystal oscillator. The function of this circuit is to provide a clock for the microcontroller. You could also use Spehro's Suggestion and use an external crystal oscillator. That combines a crystal and a circuit containing everything that's needed to make that clock …
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.
