Claim:
1. A transmission apparatus configured to extract reception data and a first clock from a received signal and transmit the reception data based on a second clock synchronized with the first clock, the transmission apparatus comprising: a detector configured to detect a frequency difference between the first clock and the second clock; a selector configured to select parallel data according to the frequency difference from a plurality of parallel data obtained by shifting bit patterns formed by bits of continuing “0” and continuing “1” by different number of the bits with each other, and a converter configured to convert the parallel data selected by the selector into serial data so as to be the second clock, wherein, in a case where the frequency difference is equal to or larger than a predetermined value, the selector selects the parallel data such that a phase of the second clock is shifted to be larger than the phase of the second clock in a case where the frequency difference is smaller than the predetermined value.
