Abstract
Introduction. The effective method of vibrational frequency stability increasing of the piezoresonant devices based on the principles of compensating of external vibrational frequency influences due to extension of information volume of PRU original signals in a mode of the QR multifrequency excitation is offered. The results. The analysis of a frequency modulated signal range of crystal oscillators of HF and UHF RF spectrums in the conditions of sinusoidal and accidental broadband mechanical destabilizing actions is carried out. The quantitative estimates of collateral spectrum components levels of an output signal for standard parameters of crystal oscillators, and also phase jitter are given using XO in digital systems. Conclusions. It is shown that use of the offered method of external vibrational frequency influences compensating allows to reduce vibrational mechanical sensitivity of PRU more than by 30 times without essential constructive and technological expenses.
