Working Principle

The 7W-25.000625MHz-T oscillator is a type of crystal oscillator, which is a circuit that generates a periodic electrical signal using a vibrating crystal. The crystal acts as a resonance element, resonating at a specific frequency when energized with an alternating current.The 7W-25.000625MHz-T oscillator consists of a piezoelectric quartz crystal, two capacitors, and one resistor. The quartz crystal is the active element in the oscillator, and it is responsible for generating the oscillating signal. The capacitors and resistor form a tank circuit that is tuned to the frequency of the quartz crystal, providing an oscillating voltage across the crystal. When the oscillator is energized, the quartz crystal will begin to vibrate at its resonant frequency, causing the voltage across the tank circuit to oscillate at the same frequency. This oscillating voltage is then used to generate an output signal.
