Working Principle

The working principle of SIT3822AC-2D-25NY is based on a phase lock loop (PLL). The PLL circuit is made up of three main components: a voltage controlled oscillator (VCO), a frequency divider, and a phase comparator. The PLL circuit works by comparing the output of the VCO with the input signal and sending an error signal back to the VCO to adjust the frequency. The frequency of the output then adjusts in order to keep the input and output in phase. The frequency of the output can then be adjusted by adding an external control voltage to the VCO.

Conclusion

SIT3822AC-2D-25NY is a versatile, low-power, high-frequency programmable oscillator. With its 16 bits frequency resolution, wide frequency range, excellent frequency stability, and low noise performance, it is ideal for many applications, such as communication systems, data acquisition systems, military and aerospace electronics, and automotive electronics. Its working principle is based on a PLL circuit, wherein the output frequency is adjusted by an external control voltage.
