Working Principle

The SIT8208AI-8F-18S-33.333300Y oscillator is a type of voltage-controlled oscillator (VCO) that uses voltage to control its output frequency. It consists of four main components: an amplifier, a voltage-variable capacitor (VVC), a resistor, and a capacitor. The amplifier is used to increase the input voltage signal to a level suitable for driving the VVC. The VVC works in conjunction with the resistor to determine the output frequency. Lastly, the capacitor is used to provide stability.

When the voltage is applied, the VVC changes its capacitance. This in turn causes the resistor to experience a change in resistance which affects the output frequency. The capacitor helps to prevent any sudden frequency changes that can result due to the rapid changes in the VVC\'s capacitance. As the voltage applied to the VVC increases or decreases, the output frequency of the oscillator increases or decreases accordingly.

In summary, the SIT8208AI-8F-18S-33.333300Y oscillator is an essential component used in a variety of applications, such as frequency-controlled current sources, frequency-controlled voltage sources, audio and video equipment, and radio frequency transmitters and receivers. It functions by utilizing a voltage-variable capacitor and resistor in conjunction with an amplifier and capacitor, to provide a stable output frequency across temperature that is carefully controlled by the input voltage.
