Abstract
A synchronization control unit for synchronizing serial-to-parallel (S/P) converters operating in parallel, or parallel-to-serial (P/S) converters operating in parallel. More specifically, first and serial-to-parallel (S/P) converters produce respectively corresponding first and second clock signals and operate in parallel. The first and second clock signals are in synchronization, and a synchronization failure occurs when the first and second clock signals fall out of synchronization. When a synchronization failure occurs, the synchronization control unit resets one of the first and second clock signals so that synchronization between the first and second clock signals is restored within a definite time period. Moreover, the synchronization control unit can perform the same operation with parallel-to-serial (P/S) converters, instead of with S/P converters.
