Working Principle

The SIT9120AI-1BF-25S155.520000D is a type of voltage-controlled oscillator (VCO). It functions by using a quartz crystal and the voltage that is applied to the chip to produce a specified frequency. The quartz crystal works in conjunction with a capacitive reactance element to stabilize the oscillation frequency. When a voltage is applied to the chip, it is compared to a reference voltage in order to calculate an error signal. This error signal is amplified and sent to the feedback circuit, which adjusts the capacitive reactance element to adjust the frequency of the VCO. By adjusting the voltage applied to the chip, it is possible to control the frequency of the VCO within a specified range.
