LM1889 TV Video Modulator
General Description The LM1889 is desigr>ed to interface audio, color difference, and luminance signals to the antenna terminals of a TV receiver. It consists of a sound subcarrier oscillator, chroma subcarrier oscillator, quadrature chroma modulators, and RF oscillators and modulators for two low-VHF channels. The LM1889 allows video information from VTR's, games, test equipment, or similar sources to be displayed on black and white or color TV receivers. When used with the MM57100 and MM53104, a complete TV game is formed.
Features ■ dc channel switching ■ 12V to 16V supply operation ■ Excellent oscillator stability ■ Low intermodulation products ■ 5 Vp-p chroma reference signal ■ May be used to encode composite video
