Working Principle

The working principle of an oscillator is based on positive feedback. It is composed of three components: an electronic amplifier, a frequency-determining device and a feedback network. The frequency-determining device of SIT8208AI-21-18E-54.000000Y oscillator comprises a high-stability quartz/ceramic resonator and an LC bandpass filter. The resonator is used to convert the electrical signal into a mechanical wave-like motion with a certain frequency, and the LC filter is used to select the required frequency and reject unwanted signals.

In operation, the amplifier converts the input voltage signal into a current signal and amplifies it. The current signal then passes through the LC filter and then the resonator, where it is converted into a mechanical wave. The oscillator then converts the mechanical wave back into voltage and amplifies it, which provides the positive feedback of oscillation. The output of the oscillator is the amplified voltage signal at the selected frequency within the limits of the LC filter.

Conclusion

In conclusion, SIT8208AI-21-18E-54.000000Y oscillator is used in a variety of applications due to its robust design and small size. It is suitable for low-power, high-temperature and high-frequency applications. Furthermore, its working principle is based on positive feedback, which consists of an electronic amplifier, a frequency-determining device and a feedback network. The frequency-determining device comprises a high-stability quartz/ceramic resonator and an LC bandpass filter, which analyse and output the required frequency signal.
