CA3217
Single Chip TV
Chroma/Luminance Processor
Description
The Harris CA3217E (Note) is a monolithic silicon integrated
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.
NOTE: Formerly Developmental Type No. TA10806.
