Integrated Circuit
Single Chip TV Chroma/Luminance Processor
Description:
The NTE844 is an integrated circuit in a 28–Lead DIP type package and contains all the required cir-
cuits functions between the video detector and the picture tube RGB driver stages of a color television
receiver. The NTE844 decodes the chrominance signals and then produces three different color sig-
nals that are internally combined with the luminance to develop the RGB signals. The picture satura-
tion, hue and brightness DC controls are externally adjustable. The AFPC, ACC, Dynamic flesh con-
trol, 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.
Features:
All chroma processing and demodulating circuitry on a single chip.
Phase–locked subcarrier regeneration utilizing sample–and–hold techniques.
Supplementary ACC with overload detector
Linear DC controls for chroma gain and tint
Dynamic “flesh correction”
Balanced chroma demodulators with low output impedance for direct coupling
Internal RF filtering
Few external components
Automatic beam limiter
Chroma luminance tracking picture control
