Experimental Analysis of Vibration-induced Phase Noise of Crystal Oscillator Circuit

Today, The vibration-induced phase noise has impact on the design of the subassembly of crystal oscillator. In this paper, the vibration-induced phase noise for sinusoidal vibration and random vibration is validated by experimental testing. The important range of vibration frequency is obtained, and it is shown that the resonant frequency increases the phase noise of crystal oscillator circuit and result in carrier frequency excursion
