Monolithic crystals have been used in a variety of consumer and industrial applications for over a century. ECS-21K-15A is an example of one such device. This particular crystal is a hermetically sealed crystal oscillator which can be used for a wide variety of purposes.

Application Field

ECS-21K-15A is ideal for a variety of applications, particularly in telecommunications and radio communications. It is used in base stations, transceivers, marine transponders, and satellite communication systems. It is also used in GPS receivers, radar systems, and digital broadcasting systems. The crystal has been tested and certified for use in critical infrastructure applications such as mobile television, broadcasting, broadcasting and navigation systems, and fiber optic systems.

ECS-21K-15A is also useful in industrial applications, such as automatic test equipment, monitoring and control systems, and navigation equipment. It can also be used in consumer applications, such as entertainment systems, gaming consoles, and home automation tools.

Working Principle

ECS-21K-15A is a hermetically sealed crystal oscillator which is designed to provide precise and stable frequencies in a variety of applications. The oscillator is made up of a AT-cut quartz prism, a metal enclosure, and electronic circuitry. The quartz prisms are securely embedded in the metal enclosure, and when the voltage is applied across it, the quartz crystal deforms, and a crystal vibrates at a precise frequency, emitting an electrical signal.

The vibration of the quartz crystal produces a frequency based on the cut of the quartz and the magnetic field strength of the metal enclosure. The frequency is stable and precise, and can be adjusted by changing the voltage or the cut of the quartz. The frequency of the signal can also be adjusted with a microcontroller or other control circuits.

The signal emitted by the oscillator is then amplified and used to drive an antenna or other receiver. The frequency of the signal is used to measure and control the transmission of radio and other electronic signals. The oscillator can be used to generate radio frequencies for a variety of purposes, such as transmitting data, telephone signals, television signals, and GPS signals.

Conclusion

ECS-21K-15A is an example of a monolithic crystal oscillator. It is used in a variety of applications, ranging from telecommunications to radio communications, industrial applications, and consumer applications. The crystal is hermetically sealed and produces a stable and precise frequency based on the voltage applied to it and the cut of the quartz. The frequency can be adjusted with a microcontroller or other control circuits, and the signal is used to measure and control the transmission of radio and other electronic signals.
