Description

The monolithic integrated circuit MGM 3000X is especially suitable as a modulator for the 48 to 860 MHz frequency range.Video recorders, cable converters, TV-converter networks, demodulators, video generators, video security systems, amateur TV-applications and personal computers.

The MGM 3000X   RF-oscillator is available at pins 3 - 7. The MGM 3000X  oscillator operates as a symmetrical Colpitts circuit. The oscillator chip ground, pin 5, should be connected to ground at the resonance circuit shielding point. An external oscillator can be injected inductively or capacitively via pins 3 and 7. The layout of the PCB should be such as to provide a minimum shielding attenuation between the oscillator pins 3 - 7 and modulator output pins 15 - 17 of approximately 80 dB.
