A data transmission system includes a plurality of signal lines (16A to 16E) that transmit transmission data or reception adjustment data for reception adjustment transmitted from a transmission-side LSI (10) to a reception-side LSI (20). The data transmission system determines which signal line among the signal lines (16A to 16E) is used to transmit the reception adjustment data. The data transmission system uses the determined signal line to transmit the reception adjustment data to the reception-side LSI (20) and uses another signal line to transmit the transmission data to the reception-side LSI (20). Thus, a phase adjustment pattern transmission processing can be performed in parallel with a normal data transmission processing, thereby enhancing a data transmission efficiency while making the reception adjustment. |
