描述 Description

The Harris CA3194E is a silicon monolithic integrated circuit designed to perform all of the signal processing functions for both he 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 5mA of current into the video output stages.
