Overview
The LC7454A/M is a data slicer IC for the Index Plus + signals. The LC7454A/M extracts the Caption and the Index Plus + data form the Vertical Blanking Period of the TV signal and send it out to the decoder IC (Usually Microcomputer). The LC7454A/M can be used to extract the Closed Caption signals, the XDS signals and the Index Plus + signals.
