The common application fields include FM radio receivers and television tuners. The device is also used as a local oscillator or sub-carrier reference oscillator in TV sound/vision systems.
 Working Principle 
The configuration of ECS-480-20-33-DU-TR contains an oscillator which produces a specific frequency. A piezoelectric crystal is set up inside oscillator, and the structure of it is the same as quartz watches. The crystal will vibrate in a certain frequency 
The crystal is connected with electrodes which has a potential difference. When the current is switched on, electrons will flow through the crystal, producing an electric field. Then, ion inside crystal will be activated, creating a mechanical force on the crystal.
The mechanical force affects the physical structure of crystal, thus releasing energy. The energy is transferred back to electric field, forming an oscillator circuit. Electronic energy will form the entire circuit, forming a feedback loop.
The magnetic field created by electrons will interact with the mechanical vibration of crystal, causing an ultrasonic vibration. The ultrasonic vibration serves as an audio frequency output for various applications.
