crystal oscillator

[¦krist·əl ′äs·ə‚lād·ər]
(electronics)
An oscillator in which the frequency of the alternating-current output is determined by the mechanical properties of a piezoelectric crystal. Also known as piezoelectric oscillator.

crystal oscillator

An oscillator that uses a quartz crystal to generate a frequency. Such devices generally output a fixed frequency, but some can be controlled by a tuning voltage over a small range. Contrast with VCO.
