Closed Caption Signal (US specifications) Extraction IC

Overview The LA7945N extracts the closed caption signal overlapped in the video signal vertical retrace period and transfers the data and clock signal to a decoder IC. This IC requires the use of either an add-on type decoder, such as the LC7458B or 7457A (for I2C), or a microcontroller type deco
