RF modulator composed of TA7673 ----- Ta7673 RF ModuLator

RF modulator composed of TA7673, TA7673 RF MODULATOR Keywords: TA7673 Composed of radio frequency modulators, TA7673, RF modulator RF modulators are an important component that televisions, recorders, satellite receivers, system converters, household computers, and gaming machines. This circuit is simple and easy to make, stable performance, reliable work, convenient to allocate all of the various circuit boards. As shown in the figure, the specific circuit of the radio frequency modulator is the specific integrated circuit TA7673 for the modulator. The 10-pin and 11 feet generate an image carrier frequency signal, 4-pin and 5 foot external LC oscillator circuit generate 6.5 MHz second. Signal signal. The audio signal is input from the 6 pin of the ICL, and the video signal is input from the 16th foot of the ICL. When the 10-pin and 11 feet are connected to the 11th foot, the circuit can be 2 feet and 15 feet in ICL. Output image carrier frequency signals of 1 to 5 channels. The circuit is loaded without debugging, but the entire circuit should be small metal box shielding.
