1 / 6 page LC7456A No.6733-1/6 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 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. Features • Low power consumption due to CMOS process • Accurate caption signal extraction using a built-in pead hold circuit and digital technology. • Power Requirement : 5V ± 10 % • Package : DIP16 SANYO Electric Co.,Ltd.
