MGM 3000X

Functional Description and Application

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.

Circuit Description

Oscillator

The RF-oscillator is available at pins 3 - 7. The 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.
