晶振在振动环境下产生严重的相位噪声恶化,由于其多学科交融的物理性质和在电子系统参考源中的应用价值而受到广泛关注。随着机电一体化设计理念的发展,研究振动环境下的信号调谐模式和探索它们独特的物理性质已经成为可能。该文从晶振的工作原理出发,分析了振动条件下相位噪声恶化的调谐原理,首次提出了一种新的晶振相位噪声振动恶化特征的物理表征方法。此外,搭建了晶振相位噪声测试系统,利用实验数据定量研究了各种输入条件对晶振电气性能的影响,并编制了相应的算法来进行求解,得出了非线性数学关系。最后,结合实验数据验证了机电一体化分析思路及物理表征方法的合理性,得到了晶振模块的振动稳健性矢量。
The vibration of the crystal produces serious deterioration of the phase noise under the environment of vibration, and has drawn extensive attention due to its multi-disciplinary blend of physical properties and application value in the electronic system reference source. With the development of the mechatronic design philosophy, it has become possible to study signal tuning modes in vibrating environments and to explore their unique physical properties. Based on the working principle of the crystal oscillator, this paper analyzes the tuning principle of the phase noise degradation under the vibration condition and proposes a new method of physical characterization of the phase noise vibration degradation characteristic. In addition, a crystal phase noise test system is set up, and the influence of various input conditions on the electrical performance of the crystal is quantitatively studied by using experimental data. Corresponding algorithms are developed to solve the problem, and the nonlinear mathematical relationship is obtained. Finally, the rationality of mechatronic analysis method and physical characterization method is verified by experimental data, and the vibrational robustness vector of the crystal oscillator module is obtained.
