Working Principle

The ECX-H27BN-74.250 works on an oscillator/amplifier circuit. At its core, the oscillator consists of a quartz crystal vibrating at a specific frequency. The crystal is connected to two amplifiers - one to amplify voltage across the crystal and the second to amplify current through it. These amplified signals are then rectified, filtered and fed back to the crystal plate. When the feedback loop is created, the crystal is forced into a vibration at a specified frequency, and oscillations are created. The outputs from this circuit are then used to generate the desired frequency signals.
