Abstract
A frequency reference oscillator device and method of providing a frequency reference signal. The oscillator device includes a first oscillator including 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 includes and a second oscillator including 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.
