Abstract: PURPOSE: A skew alignment operator between multi-lanes for the division transmission of mass data, a method therefor, and a recording medium are provided to perform a parallel process with respect to giga-level multi-lanes and transmit high-speed data with 10 giga bits or more by compensating skew phenomenon between the lanes, which is generated when transmitting the mass data to the multi-lanes. CONSTITUTION: An alignment character column comparing unit(502) detects alignment characters according to lanes from character columns received from multi-lanes, and outputs a control signal for indicating the receiving state of each lane-classified alignment character. A count control unit(509) receives the control signal of the alignment character column comparing unit(502), and outputs a control signal for informing whether an alignment character column is detected to all lanes within a skew alignment setup interval after initially detecting an alignment character from one lane. A parallel storing device control unit(503) receives the control signals of the alignment character column comparing unit(502) and the count control unit(509) and a receiving data column, and successively stores data received after the alignment character column of each lane in a setup storing device. If the storage of one interval data is completed, the parallel storing device control unit(503) successively outputs the stored data, and aligns the data column. An output selection function unit(514) outputs a receiving data column before the skew alignment of the parallel storing device is completed, and outputs the aligned data column outputted from the parallel storing device control unit(503) after the skew alignment is completed.
