U.s. Closed Caption Signal Extraction Ic

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 to CMOS technology, a smaller package size (22 pins to 16 pins), and a reduction in the external circuitry requierd. An LC8640XX series Microcontroller is needed to perform the decoding after the LC7456A has extracted the caption data from the composite Video signal. By Sanyo Semiconductor Corporation
