Integrated Circuit
NTSC System Single–Chip Color TV Signal Processor
Description:
The NTE1846 is an integrated circuit in a 52–Lead DIP type package designed for use as a color TV
signal processor. This device contains signal processing functions for video IF, sound IF, video, color,
deflection signals, on a single chip.
Combined with a tuner and a simple output stage of discreet transistors, the NTE1846 enables more
rationalized designs for color TV sets.
Features:
D Large Integration Enables Rationalization and High Reliability of Equipment and Low Power
Consumption.
D A Direct Output Pin for Sound FM Detector is Provided, Applicable to Sound Multiplexing.
D The Most Appropriate Constants can be Set by the Synchronization Separation Input Pins for
Horizontal and Vertical Deflection.
D No Horizontal Free Run Frequency Adjustments.
D Capable of AFT Defeat, Sound Muting
D DC Volume Controls Picture Quality, Contrast, Luminance, Color Saturation, Tint, and Volume.
Application:
NTSC System Color Television Set
