Definition:  An oscillator whose operating frequency(ies) is controlled by a CRYSTAL UNIT, QUARTZ. For an oscillator controlled by a device other than a crystal, see OSCILLATOR (1), NONCRYSTAL CONTROLLED. See also GENERATOR, SIGNAL; and CALIBRATOR, FREQUENCY.

Description:  1. (Electronic) An electronic device which generates alternating current power at a frequency(ies) determined by the values of certain constants in its circuits. The frequency(ies) is often an adjustable specified range. The operating frequency(ies) falls within the audio frequency spectrum (20 kilohertz and below) and/or the radio frequency spectrum (20 kilohertz and above). The frequency(ies) may be controlled by a CRYSTAL UNIT, QUARTZ, an ELECTRON TUBE, a microcircuit, a tuned inductive-capacitive circuit, or any similar device serving the same function.
