Working Principle

The CB3-7I-20M0000 oscillator is based on a crystal oscillator design. It is composed of a quartz crystal, an amplifier, a phase-locked loop, and an output driver.The quartz crystal is used as the timing element, and its natural frequency (resonance) is used to set the oscillator’s output frequency. A small current through the crystal sets the resonant frequency of the crystal, and the output is then compared to this reference frequency, and any deviation is then corrected. The amplifier is used to provide the necessary power to drive the crystal. It amplifies the signal from the crystal, and adjusts the reference frequency if necessary.The phase-locked loop is used to ensure that the output frequency is always precisely adjusted to remain in step with the reference frequency. The phase-locked loop will continuously adjust the output-frequency to remain in synchronization with the reference frequency.The output driver is used to convert the oscillator’s output into a usable form. It can provide either a square, sine, or triangle wave, depending on the model.
