DESKEWING SYSTEM

PROBLEM TO BE SOLVED: To obtain a deskewing system capable of performing End-to-End deskewing. SOLUTION: A deskewing system includes: a FIFO section 10 for adjusting a phase of transmission data 10a; a synchronizing code generating section 11 for generating a first parallel signal 11a on the basis of the transmission data 10a; a time division multiplexing circuit 13 for performing time division multiplexing upon the first parallel signal; an electric/optic conversion circuit 14 for generating an optical signal on the basis of an output signal of the time division multiplexing circuit; an optic/electric conversion circuit 17 for receiving the optical signal and converting the optical signal into an electric signal; a time division demultiplexing circuit 19 for time-dividing an output signal of the electric/optic conversion circuit to produce a second parallel signal 19a; and a deskew processing section 20 for processing the second parallel signal 19a. The deskew processing section detects a frame synchronizing pattern of the second parallel signal and notifies the synchronizing code generating section 11 about the detected pattern. The synchronizing code generating section 11 includes a skew adjusting circuit for matching skews between the first and the second parallel signals 11a and 19a. COPYRIGHT: (C)2009,JPO&INPIT
