PROBLEM TO BE SOLVED: To reduce latency in communication between transmission and receiving devices.SOLUTION: A receiving device 152 which receives data from a transmission device 172 through a plurality of lanes has: a plurality of buffers 153 which are installed to each of the plurality of lanes and store the received data; a speed difference control section 175 which outputs a first timing signal for matching the timings among the plurality of lanes on the basis of the communication speed in the lane and operation clocks of the transmission device 172 and the receiving device 152; a deskew control section which outputs a second timing signal for matching the skews among the plurality of lanes; and a control section 155 which adjusts a reading timing of the received data from the buffer 153 on the basis of the second timing signal and the difference between the reading position of the received data from the buffer 153 and the writing position of the received data to the buffer 153 in the first timing signal, at the time of adjusting frequency difference between the transmission device 172 and the receiving device 152. |
