Classification: CPC H  G | IPC G  H

Claim 1:
2. The phase synchronization device according to claim 1, wherein
the phase shifter of each of the first and second elements includes a first phase shifter and a second phase shifter,
the first phase shifter of the first element outputs, as the stage one second signal, a signal obtained by shifting a phase of the stage one third signal by the first phase shift amount to the phase interpolator of the second element,
the second phase shifter of the first element shifts the stage two first signal output from the second element by the first phase shift amount to generate the stage one fourth signal, and
the control circuit of the first element controls the first phase shift amount for each of the first phase shifter and the second phase shifter of the first element on a basis of the phase difference detected by the phase comparator.
