Working principle of LFTVXO009920BULK oscillator

The basic working principle of a LC oscillator is mainly based on two coupled coils and two capacitors. It consists of an amplifier and a resonant circuit, using the feedback mechanism of the resonant circuit. In brief, once the external-applied electrical signal to be amplified contains a signal component that coincides with the resonant frequency of the resonant circuit, it has a certain degree of oscillation, resulting in an alternating current signal (oscillating signal or oscillating output).

The LC oscillator works mainly in the form of an amplifier and a resonant circuit. Usually, the oscillator circuit contains an amplifier and a resonant circuit with capacitance and inductance. The passive resonant circuit generates a periodic signal output by the continuous energy provided by the amplifier. The voltage gain A and the feedback signal k of the amplifier give the amplifier the feedbackfunction, the output of the memory circuit is negative, and the capacitor C oscillates twice in a steady state, resulting in an oscillation frequency determined by the resonant frequency. The output of the resonanting circuit passes through the capacitor M, gains energy from the amplifier, and returns it to the resonating circuit again, so that the energy is circulated in the resonating circuit and can produce continuous oscillation.

In summary, the working principle of LFTVXO009920BULK oscillator is mainly based on two coupled coils and two capacitors, with its main working mode being amplifier and resonant circuit. It offers very reliable and stable audio and video frequency synchronization for various application fields and many electronic equipment and systems.
