Working Principle

The main principle behind the SIT1602BI-72-33E-66.666660D Oscillator is based on resonant frequency oscillation. This particular oscillator is engineered with a quartz crystal resonator and transistor-based FET amplifiers. The quartz crystal is connected to a pair of FET amplifiers and functions as a high-frequency tank circuit. The crystal is driven in the form of electrical pulses and acts as a signal source for the FETs. The quartz oscillator is designed to operate at a fixed frequency and the FETs serve to amplify the source pulses. As a result, the FETs will generate a stable oscillation with a fixed frequency determined by the quartz crystal. Consequently, the transistor-based oscillator produces a fixed frequency waveform as the output signal.
