An oscillator in which the frequency is controlled by a piezoelectric crystal. A crystal oscillator may require controlled temperature because its operating frequency is a function of temperature. Types of crystal oscillators include voltage-controlled crystal oscillators ( VCXO), temperature-compensated crystal oscillators ( TCXO), oven-controlled crystal oscillators ( OCXO), temperature-compensated-voltage controlled crystal oscillators ( TCVCXO), oven-controlled voltage-controlled crystal oscillators ( OCVCXO), microcomputer-compensated crystal oscillators ( MCXO), and rubidium crystal oscillators ( RbXO).

an oscillator that produces electrical oscillations at a frequency determined by the physical characteristics of a piezoelectric quartz crystal

an electronic device that uses the mechanical resonance

an in electronic circuit which uses the mechanical resonance of a physical crystal of piezoelectric material along with an amplifier and feedback to create an electrical signal which has a very precise and accurate frequency

a popularly used circuit block in an integrated circuit (IC), when a highly accurate clock is required

a timing device that consists of a crystal and an oscillator circuit, providing an output waveform at a specific frequency

a tuned circuit oscillator that uses a quartz crystal

A signal generator in which the frequency is controlled by a piezo-quartz crystal.

A crystal oscillator is an electronic circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency. This frequency is commonly used to keep track of time (as in quartz wristwatches), to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters.
