Abstract:
1. A transmission apparatus that transmits data and a clock to a reception apparatus, the transmission apparatus comprising: a data transmission section that transmits data to the reception apparatus; a clock transmission section that transmits a clock to the reception apparatus; a detection signal reception section that receives, from the reception apparatus, a detection signal indicating a phase difference between the data and the clock, and a waveform distortion of the data, which have been detected in the reception apparatus that has received the data transmitted by the data transmission section and the clock transmitted by the clock transmission section; and a control section that performs, based on a detection signal received by the detection signal reception section, control of an adjustment of a phase between data transmitted by the data transmission section and a clock transmitted by the clock transmission section and an adjustment of an amplitude of data transmitted by the data transmission section, wherein the detection signal is generated based on a first data, acquired by sampling the transmitted data at a rising edge of the transmitted clock, and a second data, acquired by sampling the transmitted data at a falling edge of the transmitted clock, such that the phase difference is detected based on the first data and the second data.
