Overtone crystal
WebIf a crystal has a fundamental frequency of 10 MHz, it can also oscillate at 3, 5, 7, etc times the fundamental frequency. Therefore, the oscillator can oscillate at 30 MHz, 50 MHz, 70 MHz, etc. These are the frequency's overtones. WebGenerally, crystal oscillators that operate at overtone frequencies do so using their series resonant frequency. Colpitts Quartz Crystal Oscillator Crystal oscillator circuits are …
