WebbTiming jitter in a PLL depends on the interaction of noise in the oscillator with the dynamics of the phase-locked loop because the phase difference is compensated by the feedback … WebbThe Intel® Quartus® Prime Timing Analyzer reports any phase difference between the two. In normal compensation mode, the delay introduced by the clock network is fully compensated. Only one output clock can be compensated in normal compensation mode. Figure 15. Example of Phase Relationship Between the PLL Clocks in Normal …
