Working Principles

The SIT8209AI-3F-28S-166.666666X Oscillator utilizes traditional resonators such as quartz crystals to achieve the required accuracy and stability. The resonator typically comprises a thin slice of quartz crystal with electrodes on both sides which are cut and tuned to the desired resonant frequency.The quartz oscillator is connected to an oscillation circuit which provides the signal amplification and provides the feedback necessary for oscillations. This circuit typically contains an amplifier, a frequency-determining component such as an inductor or capacitor, and a voltage controlled element to allow adjustment of the frequency.The feedback circuitry is designed to maintain the resonator frequency and to compensate for changes due to temperature and aging. The use of temperature compensation ensures the oscillator will maintain its frequency over a wide range of temperatures, thus allowing the oscillator to remain very precise and stable.The frequency at which the oscillator operates is determined by the resonator and is adjusted by the feedback circuit. By careful adjustment of the feedback circuit, the frequency of the generated oscillator signal can be set to a very high degree of precision.

Conclusion

The SIT8209AI-3F-28S-166.666666X Oscillator is an ideal choice for applications that require precise, stable signals with low phase noise.
