Working Principle

The PI6C22409WEX clock generator/PLL provides precise and low jitter clock signals by utilizing a phase-locked loop (PLL) circuit. The PLL circuit consists of a reference clock, a voltage-controlled oscillator (VCO), a programmable divider, and a phase/frequency detector (PFD). The reference clock is used to generate a known reference frequency at the input of the PLL.

The VCO produces an output frequency that is used to generate the output clock signal. The programmable divider is used to program the frequency of the VCO output by adjusting the divider ration. The output signal of the programmable divider is compared to the reference clock by the PFD and when a phase difference is detected, the PFD adjusts the charge pump voltage of the VCO to correct the frequency error.

The PI6C22409WEX has excellent jitter characteristics. The jitter is determined by the reference oscillator stability and the accuracy of the programmable divider. The PLL circuit can stabilize the reference clock jitter to provide an output signal with very low jitter.
