The LM1889 is designed 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 VTRs, games, test equipment, or similar sources to be displayed on black-and-white white, or color TV receivers. When used with the MM57100 and MM53104, a complete TV game is formed.
