Abstract:
1. A timing adjustment device comprising: a plurality of receive circuits that receive an input signal based on mutually different timings; a determination circuit that determines a first transition and a second transition of the input signal based on a received result by one or more receive circuits, among the plurality of receive circuits, that receives the input signal with adjacent timings among different timings of the plurality of receive circuits, that calculates a central timing of a period between a timing of the first transition and a timing of the second transition when determining the received input signal as valid when the received input signal includes the first transition and the second transition, that determines that the received input signal is invalid when the received input signal does not include both the first transition and the second transition, and that outputs information of the received input signal indicating valid or invalid; and an adjustment circuit that adjusts a receiving timing of the input signal based on the information so that the receiving timing of the input signal becomes close to the central timing of the period.
