  • Crystal oscillator - Wikipedia

    A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric resonator, a crystal, as its frequency-determining element. Crystal is the common term used in electronics for the frequency-determining component, a wafer of quartz crystal or ceramic with electrodes connected to it. A more accurate term for it is piezoelectric resonator.

  • Quartz Crystal Resonators » Electronics Notes

    Quartz crystals are often referred to as xtals and they are used to provide very high Q resonant elements for oscillators and filters. Quartz crystals or xtals can be cheap to produce even though they offer exceptional performance and can be used for everything from clock oscillators for microprocessors to high performance filters and highly stable oven controlled oscillators.
