Working Principle

The SIT9120AC-2C1-XXS133.333000T oscillator works on the principle of phase-lock loop to generate and stabilize a periodic signal. In this technique, the oscillator is connected to a reference frequency source. This reference frequency source sets the desired output frequency of the oscillator. As the actual output of the oscillator deviates from this reference frequency, the output is adjusted by a feedback loop to match the reference frequency.

The SIT9120AC-2C1-XXS133.333000T uses a single IC (integrated circuit) to incorporate an oscillator and amplifier. This makes it a very compact, efficient, and robust based oscillator. It is made up of many different components, including a tuned filter, voltage-controlled oscillator (VCO), divided frequency divider (DFD) and voltage-controlled amplifier (VCA).

The tuned filter of the SIT9120AC-2C1-XXS133.333000T is responsible for filtering the input frequency so that it is clean and free from external noise. This ensures that the output frequency is precisely the desired value. The VCO then takes the filtered input frequency and generates a higher frequency signal. The DFD divides this high frequency signal into two or more lower signals in order to obtain the desired output frequency. Finally, the VCA is used to amplify the output to the required level.

Conclusion

The SIT9120AC-2C1-XXS133.333000T is a highly-efficient and versatile oscillator for use in a variety of automotive infotainment and radio applications. It can be programmed to behave according to different environmental conditions, while its small size, low power consumption and superior EMI immunity make it an excellent choice for many applications. By utilizing a phase-lock loop and a combination of different electronic components, the SIT9120AC-2C1-XXS133.333000T can accurately generate and stabilize a desired output frequency.
