ABSTRACT:
An apparatus and method for converting a serial data signal into a parallel data signal based on sync signals contained within the serial data signal are provided. The serial-to-parallel data conversion apparatus includes a signal input end, a true sync signal identifier for individually identifying whether the sync signals contained in the serial data signal are true sync signals having the same positions as those of original sync signals, based on predetermined sync patterns, a false sync signal removal unit for removing from the serial data signal false sync signals which are sync signals that are not identified by the true sync signal identifier as true sync signals, and a clock generator for generating a clock signal for performing serial-to-parallel conversion of the serial data signal by using the sync signals contained in the serial data signal output from the false sync signal removal unit. Accordingly, the disclosed apparatus and method allow serial-to-parallel data conversion to be safely performed in both the case where a sync signal is not detected due to an error in the serial data and where the serial data is incorrectly detected as a sync signal because of an error.
