Title:
SERIAL/PARALLEL CONVERSION METHOD AND DEVICE FOR DATA BASED ON SYNCHRONIZATION RECOVERY
Document Type and Number:
Japanese Patent JP3021345
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To precisely recover synchronization signals for S/P conversion by discriminating whether the synchronization signals are true or false and removing the false synchronization signals from a data string.
SOLUTION: A true synchronization signal confirmation part 40 detects the synchronization signals in serial data based on the serial data and serial clocks. Then, when synchronization signal enable pulses generated in the confirmation part 40 are sent to a false synchronization signal removal part 50, the removal part 50 sends data while impressing the pulses to a pseudo synchronization signal insertion part 60 and the false synchronization signals are removed by the operation of the removal part 50. In the case that the true synchronization signals are absent, the insertion part 60 inserts pseudo synchronization signals to the position. A parallel clock generation part 20 generates parallel clocks for which the serial clocks are frequency divided into 25 based on complete synchronization signals for which the error decision of the synchronization signals is completed. Thus, an S/P conversion part 30 parallelizes the serial data.
