ABSTRACT:
A first counter detects a rising edge of a clock signal, and generates a first signal having a multiplied cycle of the clock signal.A second counter detects a falling edge of the clock signal, and generates a second signal having a multiplied cycle of the clock signal. A first line transfers the first signal, while a second line transfers the second signal. A phase comparator is connected to the first line and the second line to generate a third signal based on a phase difference between the first signal and the second signal and output the third signal to one of the circuit units.A plurality of the phase comparators are connected to the first line and the second line, and are disposed between one of the ends of the first line and the second line and one of the circuit units.
