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
