Zusammenfassung: | A reception apparatus (152) that receives data from a transmission apparatus (172) through a plurality of lanes, the reception apparatus (152) includes a plurality of buffers (153-0 to 153-7) that store received data, each of the plurality of buffers (153-0 to 153-7) being provided for each of the plurality of lanes; a speed difference controller (175) that outputs a first timing signal for adjusting timing among the plurality of lanes, based on a communication speed on the lanes and operational clocks for the transmission apparatus (172) and the reception apparatus (152); a deskew controller (160) that outputs a second timing signal for adjusting a skew among the plurality of lanes; and a controller that adjusts timing for reading the received data from the plurality of buffers (153-0 to 153-7), based on a value of the second timing signal and a difference between a read position for reading the received data from the buffers and a write position for writing the received data to the buffers, in the first timing signal, upon adjusting a frequency difference between the transmission apparatus (172) and the reception apparatus (152). |
