The quartz crystal oscillation Y1 (

The quartz crystal oscillation Y1 (quartz crystal oscillator, a general term for quartz crystal resonators and quartz crystal clock oscillators) is made using quartz crystal slices with piezoelectric effects. When the frequency of the alternating electric field is the same as the natural frequency of the quartz crystal, the vibration will become very strong, which is the reaction of crystal resonance characteristic. With this characteristic, quartz resonators can be used to replace LC(coil and capacitor) resonators, filters, etc. Quartz resonators are used in household appliances and communication equipment because of their advantages of small size, light weight, high reliability and high frequency stability. Quartz resonators are mainly used in oscillating circuits with very stable frequency because of their extremely high frequency stability.3.2.2 Working principleAs shown in Figure 3-2 below, the single chip adopts 5V power supply, and the clock circuit (i.e., the oscillator circuit) uses 11.0592MHZ crystal oscillator, which can provide a sinusoidal wave signal to the single chip as a benchmark to determine the speed of the single chip. The capacitance in the figure acts as a stabilizer. The reset circuit uses a hybrid reset circuit, which will reset automatically when the power is on.
