Working Principle of the SIT8008BI-33-33E-32.000000T Oscillator Series

The oscillator is a clock oscillator that operates using an oscillation circuit composed of the series combination of the inverter circuit and the quartz crystal oscillator. It also includes an amplifier that amplifies and feeds back the oscillation waveform generated from the quartz crystal oscillator. The oscillation frequency of the oscillator is determined by the value of the quartz crystal used. By connecting an external resistor or capacitor to the oscillation frequency adjustment terminal of the oscillator, it is possible to adjust the oscillation frequency.

The SIT8008BI-33-33E-32.000000T oscillator operates as follows: An oscillation circuit is composed of the quartz crystal oscillator, an amplifier, and an inverter circuit. An oscillator signal is generated from the quartz crystal oscillator with a frequency determined by its resonance characteristics. The amplifier then amplifies the oscillation signal, and the inverter circuit forms a positive feedback loop and passes it back to the quartz crystal oscillator. This generates an oscillation with the frequency determined by the quartz crystal oscillator.
