Clock generators, PLLs, and frequency synthesizer integrated circuits (ICs) provide a steady timing pulse from a reference signal for logic devices such as computers, microcontrollers, data communication systems, and graphic/video generators. These integrated circuits may include buffers, drivers, dividers, multipliers, multiplexers, synthesizers, fanout distributors, and prescalers.
