新型抗振晶体振荡器的分析与设计

Abstract

Abstract:

The phase noise performance of the crystal oscillator under vibration plays an important role in vehicle and airborne systems.This article discusses the phase noise of crystal oscillator under vibration.A novel anti-vibration crystal oscillator is designed using two crystal resonators to compensate acceleration sensitivity.The testing result shows that the phase noise of the novel anti-vibration crystal oscillator is better than -140 dBc/Hz at 1 kHz offset frequency after compensating acceleration sensitivity,with an improvement of 20 dB.This method is feasible and valid in reducing acceleration sensitivity of the crystal oscillator.

Key words: crystal oscillator;acceleration sensitivity;anti vibration;compensate;phase noise
