This article will discuss the application field and working principles of the ECS-200-20-5PVX.

Application Field of the ECS-200-20-5PVX

The ECS-200-20-5PVX crystal is mainly used in devices and instruments that require accurate timing for their operation. Its extremely precise and protected construction ensures it can be seamlessly incorporated into a wide range of systems for generating clock signals and boards for the two-way radio components. Owing to its flexible properties, the crystal can be used for both low and medium frequency circuits.

It is mainly employed in automotive applications such as digital dashboards, airbag systems, audio systems, immobilizer systems, ignition systems, electronic control modules, and cruise control. Additionally, it is used in computer applications as well as white goods, such as refrigerators, dishwashers, and washing machines. The crystal can also be used in life safety systems, like fire alarms and security alarms.

Working Principle of the ECS-200-20-5PVX

The ECS-200-20-5PVX crystal unit is composed of a high temperature soldering coated quartz blank along with an external circuit board substrate to which the blank is attached. The ECS-200-20-5PVX crystal has been designed in such a way to reduce size and cost. It has a double balanced crystal resonator that is fabricated from a two-piece quartz blank along with a double layer PCB. The layer of the quartz blank is protected by a passivation layer that prevents the quartz from environmental effects.

The ECS-200-20-5PVX crystal oscillator is made of two oscillator circuits, one will produce an output signal, and the other will be used for feedback. The two signals, the generated signal and the feedback signal, will be compared. The circuit is oscillating at a frequency that was determined by the external components, such as capacitors and inductors. The frequency will be maintained as long as the circuit is running.

The oscillator frequency is stable and it will not change even when other components change, due to the high frequency stability of quartz. To increase the performance of the crystal, it must be enclosed in a case or hermetically sealed. A low-pass filter is used to reduce the amplitude and improve the noise immunity of the oscillator.

Conclusion

The ECS-200-20-5PVX crystal unit is a low-cost quartz crystal device that is highly utilized in automotive, computer, communication, industrial, and consumer electronics applications. It is composed of a high temperature soldering coated quartz blank along with an external circuit board substrate, and it has a double balanced crystal resonator to reduce size and cost. The oscillator frequency is stable and it will not change even when other components change, due to the high frequency stability of quartz.
