LC7455M Closed Caption Signal Extraction IC

Ordering number : EN5680 CMOS IC LC7455A, 7455M Closed Caption Signal Extraction IC Overview The LC7455A/M extracts the closed caption signal superimposed on a video signal during the vertical return period and, under the control of a clock signal provided by the decoder IC, transfers that signal to the IC (usually a microcontroller) that decodes the closed caption data. The LC7455A/M supports four operating modes. Modes 1 and 2 can be used for XDS. In these modes, the LC7455A/M, in combinati.
