RF MODULATOR


Posted on Feb 5, 2014

Two IC rf modulators convert a suitable baseband video and audio signal up to a low VHF modulated carrier-Channel 2 through 6 in the U.S., and 1 through 3 in Japan-the LM1889 and the LM2889. Both ICs are identical regarding the rf modulation function, including pin outs, and can provide either of two rf carriers with dc switch selection of the desired carrie..
