<p>A data extraction circuit includes a determination circuit (10) which determines a sampling clock which is optimum for reproduction of reception data supplied from the exterior based on phase information of multi-phase clocks (CK1 to CKn) corresponding to an edge of the reception data. Further, the data extraction circuit includes a selection circuit (20) which selects one clock which is optimum for reproduction of the reception data according to the multi-phase clocks (CK1 to CKn) based on the result of determination in the determination circuit (10). In addition, the data extraction circuit includes a reproduction circuit (30) which reproduces the reception data according to the one optimum clock selected by the selection circuit (20). <IMAGE></p> |
