CA3194

Single Chip PAL

Luminance/Chroma Processor

May 1997

Features

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 This circuit performs all the functions needed between the video

Sample-and-Hold

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.

• DC Controls for Brightness, Contrast, and Color

Saturation Functions

• Input for Average Beam-Current Limiting

NOTE: Formerly Dev. No. TA10313.

• Contrast Control Having Excellent Tracking of

Luma and Chroma Channels

Ordering Information

• Low-lmpedance RGB Outputs with Excellent

Tracking for Direct Coupling to Video Driver
