Crystals

Crystals are solid-state electronic devices that generate electrical signals of a high degree of stability, accuracy, and reliability. Many of their functions include frequency selection, tuning, frequency synthesis, and oscillation. One of the more frequently used crystals is the ECS-080-18-20BM-JEN-TR.

Application Field

The ECS-080-18-20BM-JEN-TR crystal is designed for use in consumer and industrial applications, functioning in consumer motor drives, wireless equipment, office machines, printers, and power supplies. It is one of several high-performance crystal products specifically designed for low power consumption and low jitter.

Working Principle

The ECS-080-18-20BM-JEN-TR crystal works on the principle of sympathetic vibration. A tuned circuit consisting of an inductor and capacitor are forced to oscillate when a voltage is applied to it. When this oscillating circuit is positioned close to a precisely cut quartz crystal, it creates a sympathetic vibration. This vibration is then converted into an electrical signal of a fixed frequency by the crystal.

The ECS-080-18-20BM-JEN-TR crystal is constructed from a thin piece of quartz crystal cut to specific dimensions that are precisely tuned and maintained in a protective package. The package is designed for the specific application on the PCB, which causes additional external electric fields, thereby tuning the crystal further. The thin slice of crystal is typically cut between 10 and 20 MHz, and is capable of operating at temperatures ranging from -15°C to +85°C.

As far as accuracy and stability of the crystal are concerned, these values tend to be as high as ±30 ppm, a figure which is nearly two times higher than that of typical crystals. This figure can be further improved by the use of temperature compensations crystal, which can become as accurate as ±7 ppm. By using such a crystal, the advantages of low power consumption and low jitter can be further strengthened.
