Abstract :
The devices to be described perform in two 14 pin packages the necessary chrominance and luminance functions for the PAL system prior to chrominance demodulation. One device provides the necessary chrominance processing functions, while the other device combines luminance functions with manual chrominance control. Specifically, the chrominance IC contains the functions of sub-carrier regeneration, automatic chrominance control, H/ 2 generation and identification, color killer, and burst gating. The luminance IC provides DC operation of the contrast, saturation, and brightness controls, and the functions of beam current limiting and black level clamp.
