LC7456A Description
ENN 6733 LC7456A CMOS IC LC7456A U.S. Closed Caption Signal Extraction IC Preliminary Overview The LC7456A receives the posite 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.
LC7456A Key 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
