Crystals: ECS-250-20-30B-AEN-TR Application Field and Working Principle

Crystals are components used in electronics and electrical circuits that create a clock signal and provide precise timing for various digital systems, such as microprocessors and digital computers. The ECS-250-20-30B-AEN-TR is a quartz crystal oscillator used for frequency control and timing applications in a variety of systems. This article will discuss the application field and working principle of the ECS-250-20-30B-AEN-TR.

Application Field

The ECS-250-20-30B-AEN-TR is a perfect choice for a variety of commercial and industrial applications that require reliable and low-noise frequency and timing control. With its excellent performance with low power consumption, it is suitable for clock and time-keeping in computer systems, microprocessors, medical instruments, and other electronics products. Its output frequency is 20.000 MHz with a tolerance of ± 30.00 ppm, and it supports both fundamental and 3rd overtone modes.

Working Principle

The ECS-250-20-30B-AEN-TR uses the properties of quartz crystals to generate accurate, stable, and low-noise clock signals. Quartz is unique among other crystals because of its piezoelectric properties – when a quartz crystal is subjected to a nearby electric field, it vibrates at a frequency determined by its size and shape. Additionally, it is non-linear, meaning that its frequency response varies with the size of the electrical field.The ECS-250-20-30B-AEN-TR consists of two metal plates with an internal quartz crystal sandwiched between them. The two plates act as electrodes, and when a voltage is applied through them an electric field is generated that causes the crystal to vibrate at a specific frequency. The vibration produces a sinusoidal oscillation, known as a “clock signal”, which can be used to control the timing of digital and electrical systems.

Conclusion

The ECS-250-20-30B-AEN-TR is a quartz crystal oscillator with an output frequency of 20.000 MHz and a tolerance of ± 30.00 ppm. It is suitable for low-noise frequency and timing control in a variety of commercial and industrial applications, such as computer systems, medical instruments, and microprocessors. It works by utilizing the piezoelectric properties of quartz and creating an electrical field to vibrate the crystal at a specific frequency, producing a sinusoidal oscillation, or “clock signal”, which can be used in timing and frequency control.
