Beschreibung
Zusammenfassung:	The invention provides a crystal controlled oscillator that obtains oscillation outputs with high frequency stability. The crystal controlled oscillator includes an oscillator circuit, a temperature detector for an oscillator, a heating unit for the oscillator, a temperature detector for the oscillator circuit, and a heating unit for the oscillator circuit. The oscillator circuit is use for making the crystal oscillator oscillate. The temperature detector for the oscillator is used for detecting the temperature of an environment where the crystal oscillator is placed. The heating unit for the oscillator is used for controlling an output of the crystal oscillator based on the temperature detected by the temperature detector for the oscillator to compensate the temperature in a way that the temperature of the environment where the crystal unit is placed is constant. The temperature detector for the oscillator circuit is separated from the temperature detector for the oscillator so as to detect the temperature of an environment where the oscillator circuit is placed. The heating unit for the oscillator circuit is used for independently controlling an output of the oscillator based on the temperature detected by the temperature detector for the oscillator circuit to compensate the temperature in a way that the temperature of the environment where the oscillator circuit is placed is constant.
