Patent ID: 8582628

Claim:
A transmission device that transmits data and a clock to a reception device, the transmission device comprising: a data transmission unit that transmits data to the reception device; a clock transmission unit that transmits a clock to the reception device; a reception unit that receives data from the reception device; and a control unit that controls data transmission by the data transmission unit and clock transmission by the clock transmission unit, wherein the control unit causes the data transmission unit to transmit normal data, calibration data to detect a data reception state or a clock reception state in the reception device, calibration start instruction data to instruct the reception device to start transmission of the calibration data, and transmission instruction data to instruct the reception device to send out calibration sample data that the reception device obtained by sampling the calibration data, respectively, to the reception device at predetermined timings; and the control unit controls, when the reception unit receives the calibration sample data sent out from the reception device, any one or more of an adjustment of a phase between the data transmitted by the data transmission unit and the clock transmitted by the clock transmission unit, an adjustment of an amplitude of the data transmitted by the data transmission unit, an adjustment of a duty of the data transmitted by the data transmission unit, and an adjustment of a duty of the clock transmitted by the clock transmission unit based on the received calibration sample data.
