Working Principle

The working principle of ASCO-29.4912MHZ-LB-T3 quartz crystal oscillator mainly depends on the piezoelectric effect. Quartz crystal has the piezoelectric effect, which is mainly due to the close atomic structure of quartz crystal and the strong electric field gradient with respect to the charge inside and outside the quartz crystal. The quartz crystal can oscillate on its own if it is provided with an alternating current of a certain frequency. Due to the mechanical damping, the quartz crystal decrease its vibration amplitude gradually, and the oscillation stops when the amplitude reaches the lowest point.

The working process of the ASCO-29.4912MHZ-LB-T3 oscillator is as follows: the input voltage is amplified, and the amplified voltage is applied to the quartz crystal, which generates mechanical vibration. The oscillation frequency is determined by the specific mass of the certain quartz crystal. The fluctuation voltage is generated on the electrostatic capacitor and resistor connected to the quartz crystal, and is sent to the output terminal after being amplified. The frequency of the output signal is exactly the oscillation frequency of the quartz crystal.

The characteristics of ASCO-29.4912MHZ-LB-T3 quartz crystal oscillator are as follows: it provides high frequency stability as it is not easily affected by environmental temperature and resistivity variation. It has wide operating temperature range because of its excellent temperature performance, and the output impedance is high, so the signal-to-noise ratio is also better. In addition, its frequency stability is very good, so it is widely used in communication, military, aerospace and other industrial applications.
