What is Crystal oscillator?
A '''crystal oscillator''', or system [[crystal]], is a part of a computer. The [[computer]] uses it like a clock to keep track of time. It makes use of the mechanical [[resonance]] of the vibrating crystal, which has [[Piezoelectricity|piezoelectric]] properties, in order to obtain an electric signal with a high-precision frequency. Crystal [[Oscillation|oscillators]] are considered superior to ceramic resonators as they have higher stability, higher quality, lower cost and are smaller in size.<ref>{{Cite web|last=Electrical4U|title=Crystal Oscillator: Circuit, Frequency & Working Principle {{!}} Electrical4U|url=https://www.electrical4u.com/crystal-oscillator/|access-date=2021-11-19|website=|language=en-US}}</ref> These oscillators are usually made of Quartz crystal, even though other substances like Rochelle salt and Tourmaline exhibit the piezoelectric effect because, quartz is inexpensive, naturally-available and mechanically-strong when compared to others.<ref>{{Cite web|title=What is a Crystal Oscillator? - Definition from Techopedia|url=http://www.techopedia.com/definition/2245/crystal-oscillator|access-date=2021-11-19|website=Techopedia.com|language=en}}</ref> == References == {{reflist}} [[Category:Computer hardware]] [[Category:Electronic circuits]] [[Category:Electronic components]]
