LC7456A Datasheet (Sanyo Semicon Device) - U.S. Closed Caption Signal Extraction

LC7456A, U.S. Closed Caption Signal Extraction

Ordering number : ENN 6733 LC7456A CMOS IC LC7456A U.S.

Closed Caption Signal Extraction IC Preliminary Overview The LC7456A receives the composite video signal from the V / C (Video Chroma) signal processor and extracts the closed caption data.

This data and a clock signal, generated by an on-chip PLL, are then sent to the decoder IC.

The LC7456A is a CMOS version of the LA7945 IC also currently in production.

The differences between the LA7945 and the LC7456A are a change from Bipolar t
