Abstract
The clock edge detection circuit is equipped with a first delay circuit that delays a first clock signal and outputs a first delay clock signal, a second delay circuit that delays a second clock signal and outputs a second delay clock signal, a first retaining circuit that retains a level of the first delay clock signal at an edge of the second clock signal, a second retaining circuit that retains a level of the first clock signal at an edge of the second delay clock signal, and a logical circuit that outputs, based on the output signals of the first and second retaining circuits, a detection signal representing whether or not an edge of the first clock signal and an edge of the second clock signal are within a predetermined time range.
