Working Principle

The 655E12506A3T oscillator is a quartz crystal resonator which provides a stable timing reference when powered by an AC or DC supply. The quartz crystal works in a similar way to a tuning fork, vibrating when an AC signal is applied. The exact frequency of the oscillation is determined by the geometry of the quartz crystal – this frequency remains extremely stable over a wide range of temperatures and under varying environmental conditions, preventing drift and maintaining extremely precise frequency accuracy.

The quartz crystal is connected in series with a resonant circuit and an oscillator circuit, with the frequency of oscillation determined by the resonant circuit. The output of the oscillator circuit is fed into a buffer amplifier, which provides improved frequency stability and reduces noise levels by cleaning up the signal of any spurious harmonics. Finally, the output of the buffer amplifier can be used to clock other devices or provide a timekeeping reference.
