Software-based PLL model: analysis and applications

WebOct 1, 2010 · I've a design in which the clock is coming from a non-dedicated clock pin (PIN_AJ16). I've to generate a divide-by-2 clock and I read in the forum the best way is to use PLL. PLL can be driven from Global clock lines or dedicated clock pins. So, I instantiated a ALTCLKCTRL megafunction to route the pin on global clock line and then use that as ... WebThe phase-locked loop (PLL) is an interesting device. As shown in Figure 3-11, it consists of a phase detector, VCO, and low-pass filter.This comprises a servo loop, where the VCO is phase-locked to the input signal and oscillates at the same frequency. If there is a phase or frequency difference between the two sources, the phase detector produces an output … eagle eat snake

WebZigBee. PLL Design. A Phase-Locked Loop (PLL) is a closed-loop circuit that compares its output phase with the phase of an incoming reference signal and adjusts itself until both are aligned, i.e., the PLL output's phase is "locked" to that of the input reference. Once the loop is locked (the phase ... WebThe motivation for out project was to gain a better understanding of the nonlinear behaviour of the Phase-Locked Loop (PLL) circuit. The existence of chaos in an ordinary PLL circuit being used for frequency demodulation was demonstrated over a decade ago [1], and in this presentation some of the previous results and recent developments will be demonstrated …
