<p>PURPOSE: To suppress the increase of the scale of a circuit for separating reception data into plural data even when the insertion position of pulse stuffing is not fixed. CONSTITUTION: A frame synchronization detection part 16 obtains frame synchronization by detecting a frame synchronization word from the reception data SRD and a control part 19 detects the insertion position of the pulse stuffing inserted to the reception data RD based on octet clock signals CK8K outputted from a timing generation part 18. A D flip-flop circuit 12, an OR circuit 13, a selector 14 and the control part 19 obtain the reception data SRD for which the insertion position of the pulse stuffing is fixed to a predetermined position by rearranging the frame pattern of the reception data RD based on the detection output of the frame synchronization detection part 16 and the detection output of the insertion position of the pulse stuffing.</p> |
