A multiphase clock generation circuit includes: a first frequency divider to generate a first intermediate clock and a second intermediate clock; a second frequency divider to generate output clocks of a first group including a first output clock and a second output clock; a third frequency divider to generate output clocks of a second group including a third output clock and a fourth output clock; a selector to supply one of the second intermediate clock and a value to the third frequency divider in response to a switching signal; an error detection circuit to detect an error in a phase relationship between the output clock of the first group and the output clock of the second group; and a re-reset circuit to output the switching signal to the selector based on the error. |
