Working Principle

The SIT1602BC-73-33N-66.666660G oscillator mainly uses a sound-pressure micro-vibration quartz crystal oscillator. The frequency of the crystal oscillator is mainly determined by its equivalent mass and the elastic coefficient of the quartz crystal material. The exact frequency is divided into two parts: one is the frequency that the quartz crystal provides naturally, and the other is the frequency that is controlled by enhancing the amplitude of the quartz crystal at the required frequency. The basic structure of SIT1602BC-73-33N-66.666660G oscillator consists of temperature-compensated crystal oscillator, frequency-determining resistor (R), precision adjustable resistance (Potentiometer, POT), oscillator output buffer, and other components.

In the SIT1602BC-73-33N-66.666660G oscillator circuit, the quartz crystal oscillator is used as the basic frequency-determining element. When working, the frequency-determining resistor (R) and precision adjustable resistance (potentiometer, POT) cooperate to determine the frequency by adjusting the amplitude of the quartz crystal accurately to the required frequency. The oscillator output buffer is used to amplify and buffer the output signal. This ensures that the output waveform is a sine wave with a small noise and low distortion factor.

In summary, the SIT1602BC-73-33N-66.666660G oscillator is an economical and easy to use oscillator for the operating temperature range of -40°C to 85°C. It consists of temperature-compensated crystal oscillator, frequency resistor (R), precision adjustable resistance (POT) and oscillator output buffer. It is widely used in modern wireless communication equipment for precise frequency and time control.
