NTE986
Integrated Circuit−Linear
Single Chip TV Chroma Processor/Demodulator
Description:
The NTE986 is a monolithic silicon integrated circuit in a 24−Lead DIP type package that performs
the complete chroma processor and demodulating functions for color TV. This simple chip contains
all the features of the NTE797 chroma processor and the NTE1176 chroma demodulator.
Features:
D Phase Locked Subcarrier Regeneration Utilizing Sample and Hold Techniques.
D All Chroma Processing and Demodulating Circuitry on a Single Chip
D Supplementary ACC with Overload Detector to Prevent Over Saturation of the Picture Tube
D Linear DC Controls for Chroma Gain and Tint
D Dynamic “Flesh Correction” − Corrects Green and Purple Flesh Colors Without Affecting Primary
Colors.
D Balanced Chroma Demodulators with Low Output Impedance for Direct Coupling
D Internal RF Filtering
D Requires Few External Components
D Low System Dissipation − 0.5W Nominal
