Working Principle

The 591FC148M500DGR oscillator operates on a Pierce oscillator circuit principle. The circuit consists of two NPN transistors and an external loop filter. The active loop filter is integrated in the oscillator circuit to reduce the noise and loading on the output signal. The transistors are connected to a quartz crystal, which is used to generate the output signal.

The output signal of the oscillator is generated by charging and discharging the crystal. The circuit is configured so that the transistors alternately charge and discharge the crystal, which causes the crystal to vibrate and generate an oscillating voltage. This oscillating voltage is then amplified and used to drive the output signal. This process is then repeated continuously, generating a periodic signal at the output.
