Abstract
A clock generation system for deriving a second clock signal from a first clock signal with a predetermined clock frequency ratio, where the first clock frequency is divided by a first integer, the second clock signal is divided by a second integer, an error signal is generated by comparing the division results, a voltage-controlled oscillator is controlled in dependence on said error signal to generate the second clock signal, and a switch is provided for alternately switching each of the clock signals to a single frequency divider or for alternately switching one of the clock signals to one of two frequency dividers and simultaneously switching the other one of the clock signals to the other one of the two frequency dividers to eliminate errors that may result from processing the two clock signals in different circuit sections.
