Principle of Operation

The 595PH19M4400DG oscillator works on a principle known as "phase-locked loop" (PLL). This type of oscillator works by keeping an oscillator signal synchronized with the reference signal input, by using feedback from the phase detectors. It achieves this by adjusting the oscillator\'s frequency until its phase matches the reference signal\'s phase, and thus locks it with the reference signal.

The PLL allows highly precise control over the frequency and amplitude of the generated oscillator signal. This is because of the inherent high stability of the PLL, which is due to the feedback loop that ensures a perfect match between the reference signal and the oscillator signal. The feedback loop also inherently reduces the amount of noise present in the generated oscillator signal, resulting in a purer signal.
