Zusammenfassung:A crystal controlled oscillator includes a crystal unit, an oscillator circuit, a temperature detector for crystal unit, a heating unit for crystal unit, a temperature detector for oscillator circuit, and a heating unit for oscillator circuit. The heating unit for crystal unit is configured to control an output of the crystal unit based on a temperature detected by the temperature detector for crystal unit to compensate the temperature of the atmosphere where the crystal unit is placed to be constant. An output of the heating unit for oscillator circuit is controlled independently from the heating unit for crystal unit based on a temperature detected by the temperature detector for oscillator circuit to compensate the temperature of the atmosphere where the oscillator circuit is placed to be constant.
