Embodiment
[0037] An embodiment of the present invention provides a voltage-controlled crystal oscillator device for an atomic frequency standard. The voltage-controlled crystal oscillator device is suitable for any atomic frequency standard (such as figure 1 atomic frequency scale shown). The atomic frequency standard includes a quantum system for providing quantum frequency identification signals, and a synchronization phase identification module for synchronous phase identification of the quantum frequency identification signals provided by the quantum system and reference signals to obtain phase identification results. Based on this, see figure 2 , the voltage-controlled crystal oscillator device provided by the embodiment of the present invention includes a VCXO100. The voltage-controlled crystal oscillator device also includes:
[0038] The first voltage reference 101 is in the same working environment as the VCXO 100 and is used to provide the VCXO 100 with a preset first offse...
