Working Principle

The SIT1602BI-12-18N-33.300000E oscillator operates in a closed-loop crystal oscillation feedback circuit. This circuit consists of an active device such as a transistor or an operational amplifier, a tank circuit consisting of a quartz crystal, and a feedback network. The active device is used to generate the oscillation frequency and the tank circuit is used to convert the generated frequency into a stable signal. When voltage is supplied to the oscillator circuit, a signal current will flow through the transistor or amplifier, and the quartz crystal. This current interacts with the piezoelectric effect of the quartz crystal to produce a resonant output frequency that is proportional to the crystal\'s nominal frequency. The feedback network further stabilizes the output frequency. The active device amplifies the output signal and sends it back to the quartz crystal to maintain the oscillations in the circuit and ensure the stability of the output frequency.

Conclusion

The SIT1602BI-12-18N-33.300000E oscillator is a reliable and precise oscillator that is able to operate in harsh environments. It is used in a variety of industries and applications, such as aircraft, military, and medical systems. Its working principle is based on a closed-loop feedback circuit of an active device, a quartz crystal, and a feedback network. When supplied with voltage, this circuit produces a stable resonant output frequency that is proportional to the crystal\'s nominal frequency.
