Abstract

A receiving circuit includes: a detector configured to detect a position at which logics of first data and second data acquired by sampling received data using two clocks having mutually-different phases do not match each other as an edge; and an adjustment circuit configured to perform an adjustment causing an internal clock frequency to be close to a data frequency in the received data based on a first probability that logics of third data in a next cycle of the first data and the second data match each other and a second probability that logics of fourth data in a next cycle of the second data and the third data match each other.
