Clock Generation Using PLL Frequency Synthesizers DigiKey

WebThe design of clock generation circuitry being used as a part of a high-performance microprocessor chip set is described. A self-calibrating tapped delay line is used to generate four nonoverlapping clock phases of a system clock. A charge-pump phase-locked loop (PLL) calibrates the delay per stage of the delay line. Using this technique, it is possible … WebA simplified clock generation circuit is shown schematically in figure 1. The circuit is a phase locked loop consisting of a reference input, phase detector, gain stage and a low pass filter. The actual components used in practical PLL implementations vary but the overall operation is the same and this circuit can be used to analyze their behavior. portable high power car vacuum cleaner
