Abstract: PURPOSE: To produce a phase detector which infinitely operates to inputted data bit rate and from which outputted phase information is outputted in a state where it is easily matched with a digital circuit. CONSTITUTION: This detector is provided with D flip flops U1 and U3 for inputting NRZ data, a receiver U4 for inputting a clock pulse CP which executes re-timing, a D flip flop U2 for inputting the output of U1, an exclusive OR and NOR gate U5 and an exclusive NOR gate U6.
