【摘要】：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。
[Abstract]:Crystal oscillator has caused serious phase noise deterioration in the vibration environment. It has attracted wide attention due to its physical properties of multidisciplinary blending and its application value in electronic system reference sources. With the development of mechatronics design concept, it is possible to study the signal tuning mode and explore their unique physical properties in vibration environment. Based on the working principle of crystal oscillator, the tuning principle of phase noise deterioration under vibration condition is analyzed, and a new physical representation method of phase noise deterioration characteristic is proposed for the first time. In addition, the phase noise measurement system of crystal oscillator is built, and the influence of various input conditions on the electrical performance of crystal oscillator is quantitatively studied by using the experimental data, and the corresponding algorithm is developed to solve the problem, and the nonlinear mathematical relationship is obtained. Finally, the rationality of the mechatronics analysis method and the physical representation method is verified by the experimental data, and the vibration robustness vector of the crystal oscillator module is obtained.
