Working Principle of the SIT9002AI-38H18DK

The SIT9002AI-38H18DK is a voltage controlled oscillator (VCO) that works on the principle of a varactor diode. A varactor diode is a type of diode whose capacitance varies depending on the applied voltage. This variation in capacitance is used to generate the oscillations.

The VCO of the SIT9002AI-38H18DK consists of an inductor and a varactor diode connected in a tank circuit and driven by an amplifier connected to a voltage source. The voltage source will adjust the capacitance of the varactor diode, resulting in a change in the frequency of the oscillations. This frequency can be set as desired by adjusting the voltage from the voltage source.

The SIT9002AI-38H18DK also has a trimmable frequency adjustment pin, which allows for more precise control over the oscillation frequency. This trimmable frequency pin is useful in applications where precise control of the oscillation frequency is needed, such as in audio systems.
