LM2889 TV Video Modulator

General Description

The LM2889 is designed to interface audio and video sig-

nals to the antenna terminals of a TV receiver It consists of

a sound subcarrier oscillator and FM modulator video

clamp and RF oscillators and modulators for two low-VHF

channels

The LM2889 allows video information from VTRs video disk

systems games test equipment or similar sources to be

displayed on black and white or color TV receivers
