Title (EN) FREQUENCY REFERENCE OSCILLATOR DEVICE AND METHOD OF STABILIZING A FREQUENCY EFERENCE SIGNAL
(FR) DISPOSITIF OSCILLATEUR DE RÉFÉRENCE DE FRÉQUENCE ET PROCÉDÉ DE STABILISATION D'UN SIGNAL DE RÉFÉRENCE DE FRÉQUENCE
Abstract:
(EN) The invention relates to a frequency reference oscillator device and method of providing a frequency reference signal. The oscillator device comprises a first oscillator comprising a first resonator having first long-term stability and a first frequency-vs-temperature turnover temperature, the first oscillator being capable of providing a first frequency signal. Further, the device comprises and a second oscillator comprising a second resonator having second long-term stability, which is inferior to the first long-term stability, and a second frequency-vs-temperature turnover temperature, the second oscillator being capable of providing a second frequency signal. There is also provided a thermostatic controller for adjusting the temperature of the first resonator essentially to said first turnover temperature and the temperature of the second resonator essentially to said second turnover temperature, and a stability control circuit configured to use the first frequency signal for adjusting the second oscillator for providing a temperature stabilized and long-term stabilized output frequency signal.
(FR) L'invention concerne un dispositif oscillateur de référence de fréquence et un procédé de fourniture d'un signal de référence de fréquence. Le dispositif oscillateur comprend un premier oscillateur comprenant un premier résonateur ayant une première stabilité à long terme et une première température de retournement fréquence/température, le premier oscillateur étant apte à fournir un premier signal de fréquence. En outre, le dispositif comprend un second oscillateur comprenant un second résonateur ayant une seconde stabilité à long terme qui est inférieure à la première stabilité à long terme et une seconde température de retournement fréquence/température, le second oscillateur étant apte à fournir un second signal de fréquence. L'invention concerne également un dispositif de commande thermostatique afin d'ajuster la température du premier résonateur essentiellement à ladite première température de retournement et la température du second résonateur essentiellement à ladite seconde température de retournement, ainsi qu'un circuit de commande de stabilité conçu pour utiliser le premier signal de fréquence afin d'ajuster le second oscillateur pour fournir un signal de fréquence de sortie stabilisé à long terme et stabilisé en température.
