Working Principle of 377NB5C2457T Oscillator

The working principle of a 377NB5C2457T oscillator is fairly simple. It is based on the principle of voltage-controlled oscillation (VCO), in which the frequency of the output signal is determined by the control voltage applied to the oscillator. In the case of the 377NB5C2457T, the control voltage is generated from an external reference clock signal. This reference signal is applied to the VCO through an on-chip phase/frequency comparator. The frequency of the VCO is controlled by an on-chip digital frequency counter, which measures the output frequency of the VCO against the reference signal. The frequency counter in turn provides the appropriate control voltage to the VCO, thus controlling its frequency.The 377NB5C2457T also incorporates a low pass filter on the output stage of the oscillator. This filter serves to reduce the noise generated by the oscillator, which is necessary for most applications. The noise reduction achieved by the filter also helps to ensure that the output frequency remains stable and accurate.
