As for working principle, SIT8008BIL2-25N uses a phase-locked loop (PLL) to convert an input frequency and supply voltage into an adjustable output frequency. The PLL is a closed-loop system that is composed of a phase comparator, a low pass filter, a voltage-controlled oscillator (VCO), a frequency divider and a feed-back loop. The phase comparator compares the phase and amplitude of the reference frequency with the output of the frequency divider and generates a voltage error signal. Then, the low pass filter converts this voltage error signal into a control voltage. The control voltage is applied to the VCO to control its frequency. Finally, the feedback loop locks the output frequency to the reference frequency. The resulting output frequency is proportional to the input frequency multiplied by the division factor of the frequency divider.

In summary, SIT8008BIL2-25N is a programmable oscillator designed for applications in telecoms, satellite tracking & navigation, digital TV and other industrial applications, making it suitable for use in a wide range of applications. It works on the principle of utilizing a phase-locked loop to convert an input frequency and supply voltage into a adjustable output frequency, and it has remarkable features such as wide range of output levels, various package types, low jitter and low power consumption.
