由于振荡器的性能总是比它所用的石英谐振器的性能要差,所以,谐振器是晶体振荡器的心脏。设计优良振荡器的重要目标是尽量减小振荡器和谐振器之间的这种性能差异。为了实现这个目标,充分地了解谐振器的性能是十分必要的。这就要了解谐振器的技术条件,以石英谐振器和振荡器的技术条件为基础的计算和振荡器的电路参数。本文对现有谐振器的技术条件作了阐明,并补充了一些有关振荡器和谐振器性能和电路的概念。文章内容特別适合于采用五次泛音低C_1的SC切精密晶体振荡器。
The resonator is the heart of a crystal oscillator because its performance is always worse than the performance of the quartz resonator it uses. An important goal in designing an excellent oscillator is to minimize this performance difference between the oscillator and the resonator. In order to achieve this goal, fully understand the performance of the resonator is very necessary. It is necessary to understand the technical conditions of the resonator, the calculation of the resonator and the circuit parameters of the oscillator based on the technical conditions of the quartz resonator and the oscillator. In this paper, the technical conditions of existing resonators are clarified, and some concepts about oscillator and resonator performance and circuits are added. Article content is particularly suitable for the SC harmonic precision crystal oscillator using the fifth overtone low C_1.
