Abstract

The present technology relates to a first edge detector that detects whether there is an edge of a second clock signal in one cycle of a first clock signal. A second edge detector detects whether there is an edge of the first clock signal in one cycle of the second clock signal. The logic circuit performs a logical operation on a detection result from the first edge detector and a detection result from the second edge detector. The present technology can be applied to a circuit or the like that detects a locked state of a PLL circuit, for example.
