.Data Sheet.co.kr Semiconductor May 1997 DF NDE ES WD Single Chip PAL Luminance/Chroma Processor Features - All PAL Luminance and Chrominance Processing Circuitry on a Single Chip in a 24-Lead Plastic Package - Phase-Locked Subcarrier Regeneration Utilizing Sample-and-Hold - DC Controls for Brightness, Contrast, and Color Saturation Functions - Input for Average Beam-Current Limiting - Contrast Control Having Excellent Tracking of Luma and Chroma Channels - Low-lmpedance RGB Outputs with Excellent Tracking for Direct Coupling to Video Driver Circuitry Description The Harris CA3194E is a silicon monolithic integrated circuit designed to perform all of the signal processing functions for both the chroma and luminance signals of PAL color television receivers. This circuit performs all the functions needed between the video detector and the video RGB output stages. DC contrast, brightness, and saturation controls and average beam limiting functions are included. The RGB buffer stages are capable of delivering 5m A of current into the video output stages.
