Crystals are widely used in the form of oscillators, filters, multipliers and other components in electronic devices. Among the many different types of crystals, one of the widely used crystals is ECS-40-20-7SX-TR.

ECS-40-20-7SX-TR is an extremely small size and ultra-low profile Crystals. It has an operating temperature range of -40 to +85 degrees Celsius, controlling the displacement of frequency by +/-7ppm at 25 degrees Celsius. It has an excellent frequency stability and a long working life that can last up to 10 years.

ECS-40-20-7SX-TR crystals are available in a variety of package sizes, ranging from 2.0 x 1.6 to 6.0 x 4.4 millimeters, making it suitable for a wide range of applications.

ECS-40-20-7SX-TR crystals are ideal for use in GSM, GPS, Bluetooth and other digital communication systems, as well as consumer electronics. In these systems, the crystals convert digital signals into a series of periodic waveforms which can be transmitted and received across different devices. ECS-40-20-7SX-TR crystals also provide an accurate frequency reference for frequency hopping and clock synchronization.

The working principle of the ECS-40-20-7SX-TR crystal oscillator is based on the property of the quartz crystal to oscillate at a specific and constant frequency when it is subjected to an alternating electric field. The crystal vibrates when molecules inside the crystal move in response to an electric field, and the frequency of the vibration determines the frequency of the output.

ECS-40-20-7SX-TR crystals are made up of two pieces of cut quartz crystal, mounted and held in position by metal electrodes. When electric current is applied to the electrodes, the two pieces of quartz vibrate at a certain frequency determined by the size and shape of the crystal. This creates an electrical signal with the same frequency, which can be used to create an accurate reference for digital communication and timing control.

The performance of ECS-40-20-7SX-TR crystals are characterized by the frequency stability over changes in temperature, voltage and time. The frequency tolerance of the crystal oscillator should be within +/-7ppm at 25 degrees Celsius, in order to maintain the precise frequency output of the crystal oscillator, for reliable operation.

In addition, the ECS-40-20-7SX-TR crystals are designed for ultra-low profile and EMI/EMC protection, which is important in applications that require high level of electronic immunity and immunity from electromagnetic disturbancest.

In conclusion, ECS-40-20-7SX-TR crystal oscillators are important for providing accurate, stable and reliable frequency reference for digital communication and other timing and control applications. The excellent frequency stability, ultra-low profile and wide range of packages make these crystals suitable for applications ranging from consumer electronics to digital communication systems.
