Features

Description

• All Chroma Processing and Demodulating Circuitry The Harris CA3217E (Note) is a monolithic silicon integrated

on a Single Chip in a 28 Lead Plastic Package

circuit. It contains all the required circuit functions between

the video detector and the picture tube RGB driver stages of

a color television receiver. The CA3217E decodes the

chrominance signals and then produces three different color

signals that are internally combined with the luminance to

develop the RGB signals. The picture saturation, hue and

brightness DC controls are externally adjustable by the

viewers. The AFPC, ACC, Dynamic flesh control, Beam

limiting and Gate black level (Brightness) control are servo

loops used to stabilize the RGB output and reduce frequent

manual adjustment. The automatic beam limiter circuit

reduces picture contrast and brightness to prevent

excessive drive output at the picture tube.

• Phase Locked Subcarrier Regeneration Utilizing

Sample and Hold Techniques

• Supplementary ACC with Overload Detector to

Prevent Over Saturation of the Picture Tube

• Linear DC Controls for Chroma Gain and Tint

• Dynamic “Flesh Correction” - Corrects Purple and

Green Flesh Colors without Affecting Primary Colors

• Balanced Chroma Demodulators with Low Output

Impedance for Direct Coupling

• Internal RF Filtering

NOTE: Formerly Developmental Type No. TA10806.

• Requires Few External Components

• Automatic Beam Limiter

• Chroma Luminance Tracking Picture Control
