Single Chip PAL
Luminance/Chroma Processor
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, 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.
