Receiving apparatus, data transmission system and receiving method

A receiving apparatus for receiving data sequences each of which comprises a plurality of data blocks from a plurality of transmission lines, respectively, the apparatus comprising:

• a plurality of elastic buffers into each of which the corresponding data sequence is written, a predetermined number of consecutive timing control symbols being inserted into the respective data sequences as markers for data blocks to be read from the respective data sequences at the same cycle, the elastic buffers that adjust numbers of the timing control symbols included in the written data sequences, respectively, the elastic buffers from which the data sequences in each of which the number of the timing control symbols has been adjusted are read in synchronization with a reading clock;
• and
• a deskew circuit into which the data sequences read from the elastic buffers are written, the deskew circuit that adjusts the number of the timing control symbols included in each data sequence so as to be equal to the predetermined number, the deskew circuit from which the data sequences—in each of which the number of the timing control symbols has been adjusted to be equal to the predetermined number—are read at the same cycle in synchronization with the reading clock using the timing control symbols as the markers.
