As differentiated by the drawing
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. Excludes frequency supply, telephone carrier; resonator, tuning fork; and oscillator, pulse delay.
Classification: Mounted piezoelectric crystals, quartz, designed for operating frequencies exceeding 20 mhz
