Abstract: A clock oscillator, a clock oscillator production method and use method, and a chip including the clock oscillator are provided. The clock oscillator includes a resonator, a shock-absorbing material layer, and a base, and at least a part of the shock-absorbing material layer is located between the resonator and the base. In the clock oscillator, the shock-absorbing material layer is added between the resonator and the base, and the shock-absorbing material layer can effectively prevent a mechanical wave from being conducted between the base and the resonator, so that the resonator is protected from external vibration. This can ensure, when there is external vibration, that an output frequency of the resonator is not deteriorated and improve shock absorption performance of the clock oscillator.

Abstract: A clock oscillator includes a first resonator, a second resonator, and a frequency synthesis module, where an output frequency of the first resonator is higher than an output frequency of the second resonator, the frequency synthesis module is configured to generate a synthesis frequency based on the output frequency of the first resonator and the output frequency of the second resonator, and the synthesis frequency is used as a clock frequency output by the clock oscillator. The clock oscillator uses both of the two resonators with the different output frequencies as clock signal sources, and generates a synthesized clock signal by using the frequency synthesis module.
