NTE846
Integrated Circuit
TV Video Modulator
Description:
The NTE846 is designed to interface color difference, audio, and luminance signals to the antenna
terminals of a TV receiver. It consists of a sound subcarrier oscillator, chroma subcarrier oscillator,
quatrature chroma modulators, and RF oscillators and modulators for two low–VHF channels.
The NTE846 allows video information from VTR’s test equipment, games, or similar sources to be
displayed on black and white or color TV receivers.
Features:
D DC Channel Switching
D Excellent Oscillator Stability
D 12V to 18V Supply Operation
D Low Intermodulation Products
D 5V_p–p Chroma Reference Signal
D May Be Used to Encode Composite Video
