Working principle of 345LB5C2000T oscillator
The 345LB5C2000T oscillator is mainly composed of five major components, including an oscillator circuit, a frequency divider, a stabilizing capacitor, a damping resistor and a buffer amplifier. The oscillator circuit is composed of quartz crystal and two LCDs. The frequency divider divides the original frequency generated by the quartz oscillator to meet the required frequency, and the stabilizing capacitor can filter the power supply voltage and make the output voltage more stable. The damping resistor is responsible for limiting the amplitude of the oscillation signal and the buffer amplifier is responsible for amplifying the oscillation signal. Together, these five components form the 345LB5C2000T oscillator.
The working principle of the 345LB5C2000T oscillator is very simple. The quartz crystal in the oscillator circuit vibrates at a certain frequency under an applied electric field, and generates AC signals in the form of resonance. Then the frequency divider divides the quartz oscillation frequency into the frequency required by the external circuit. After that, the stabilizing capacitor filters the power supply voltage and the damping resistor limits the amplitude of the oscillator output signal. Finally, the buffer amplifier amplifies the output signal, so that the output voltage can meet the requirements of the external circuit.
