Crystal Oscillator

Quartz Oscillator 3225 20M OSC

A crystal oscillator is a fundamental component in many electronic circuits, providing a stable and precise frequency reference. It typically consists of a quartz crystal that vibrates at a specific frequency when an electric signal is applied. These oscillators are widely used in communication systems, microcontrollers, and timing applications. In some designs, the oscillator may include multiple transistors to perform channelization or frequency division operations. Depending on the circuit requirements, a buffer amplifier can be added to isolate the oscillator from the load and prevent signal distortion. This helps maintain signal integrity and improves overall system performance.
