Crystal Oscillators - the 'heartbeat' for an MCU A quartz crystal oscillator is the 'heartbeat ' for an entire microprocessor unit (MCU). It provides the clock frequency signal that is necessary for the MCU to execute instructions. A module that contains a quartz crystal and an oscillation circuit requires a power supply for temperature and frequency adjustment output. Because the module contains active electronic components, it is considered an active crystal oscillator. It is important to note that a quartz crystal oscillator does...

A frequency-generating system for v.h.f. communication equipment
Alternatively, overtone crystals in the range 24£- 54^ Mc/s could be used, but this tends to give greater frequency errors. .... For example, the conventional series-mode overtone oscillators use tuned circuits which have a considerable effect on the frequency of the oscillator, whereas the tuning of the harmonic selector circuits has no appreciable effect on the Pierce- Colpitts oscillator frequency.
