Working Principle

The SIT8208AI-23-25E-38.400000Y oscillator functions by producing a constant output frequency through a frequency synthesis process. The oscillator is composed of a series of components, which include a voltage controlled resistor, a voltage-to-frequency converter, and a phase locked loop (PLL). A voltage is applied to the voltage controlled resistor, which causes it to vary in resistance. This varies the flow of current, which in turn affects the output frequency of the oscillator. The voltage to frequency converter then takes the varying voltage and converts it into a changing frequency, which is then passed through the PLL to further regulate the output frequency. The resulting frequency is kept constant, regardless of any changes in the input voltage.

Conclusion

The SIT8208AI-23-25E-38.400000Y oscillator, with its impressive modulation capability and wide temperature range, is an ideal choice for radio frequency and mobile telecommunications applications. Its frequency synthesis process yields a stable output frequency, making it suitable for use in a variety of applications and challenging environments.
