Single Chip PAL
Luminance/Chroma Processor
Description
• All PAL Luminance and Chrominance Processing The Harris CA3194E is a silicon monolithic integrated circuit
Circuitry on a Single Chip in a 24-Lead Plastic designed to perform all of the signal processing functions for both
Package
the chroma and luminance signals of PAL color television receivers.
• 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
This circuit performs all the functions needed between the video
detector and the video RGB output stages. DC contrast, bright-
ness, and saturation controls and average beam limiting functions
are included. The RGB buffer stages are capable of delivering
5mA of current into the video output stages.
NOTE: Formerly Dev. No. TA10313.
