Working Principle

The PCK953BD 118 uses the phase-locked loop (PLL) concept to generate its output frequencies. The PLL consists of a reference oscillator and a voltage-controlled oscillator (VCO), connected in a system of servo loops. The output of the reference oscillator is used to compare with the feedback signal provided by the VCO. The result of this comparison is a phase-error signal which is used to adjust the output frequency of the VCO.

This process can be repeated quickly and the result is a stable, high-bandwidth loop. The advantage of the PLL approach is that it can quickly and accurately adjust the VCO frequency and generate a wide variety of output frequencies. The PCK953BD 118 is designed to work maximally with multiple output frequencies, offering ultimate flexibility.

Thanks to the PLL approach, the PCK953BD 118 is able to generate accurate output frequencies with very low jitter and high accuracy. Additionally, it offers excellent EMI performance without compromising performance. Overall, the PCK953BD 118 is a great choice for any precision timing applications.
