  • Patent number: 8855242
    Abstract: A data receiving circuit includes a generating unit that generates multiple clocks with different phases from one another. The data receiving circuit includes multiple acquiring units that acquire data from a received data signal by using different clocks from one another out of the multiple clocks generated by the generating unit. The data receiving circuit includes a determining unit that determines whether the data acquired by the multiple acquiring units are consistent. The data receiving circuit includes a correcting unit that corrects the phases of the multiple clocks in a direction in which data inconsistency does not occur when the determining unit has determined that there is data inconsistent with the other data in the data acquired by the multiple acquiring units.
