Spread-spectrum clock generation circuit, integrated circuit and apparatus therefor

摘要

A spread-spectrum clock generation circuit comprises at least one comparison element; at least one charge storage device arranged to couple an output of the at least one comparison element to an input of the at least one comparison element and arranged to set a first oscillation frequency of the spread-spectrum clock generation circuit; and a switched charge storage arrangement additionally arranged to couple an output of the at least one comparison element to an input of the at least one comparison element and arranged to set a second oscillation frequency of the spread-spectrum clock generation circuit.
