LA76931 datasheet pinout


The LA76931, LA7693XJ series is a single-chip video and sound processor IC with a built-in microcontroller that supports all of the different worldwide broadcasting systems. The IC provides fully integrated solution to rationalize the design of color TV sets, increase productivity, and reduce total costs.

A video and sound processor IC, also known as an audio-video processor IC or audio-video controller IC, is an integrated circuit designed to handle both video and audio processing tasks in electronic devices such as televisions, media players, gaming consoles, and home theater systems.

1. Video Processing: These ICs often incorporate video processing functions such as video scaling, deinterlacing, noise reduction, color correction, and image enhancement. These features aim to improve the visual quality, reduce artifacts, and provide a more immersive viewing experience.

2. Audio Processing: Video and sound processor ICs also include audio processing capabilities, which may involve audio decoding, surround sound processing, equalization, audio mixing, and various audio effects. These features enhance the audio quality, spatial immersion, and overall sound performance.
