ECS-120-S-28A-TR is a frequency control product used for the synchronization of digital integration ICs and frequency modulation. Its characteristics include high frequency stability, low temperature drift, and high reliability. This article will discuss the application field and working principle of the ECS-120-S-28A-TR.

Application

The ECS-120-S-28A-TR can be used in a wide range of fields, such as wireless network synchronization and frequency control, system clock modules, core overlock control of game consoles, lcd image stabilization control, and wireless communications. In areas such as backlight dimming control, touch screen control, and GPS navigation, the frequency accuracy obtained by the ECS-120-S-28A-TR greatly enhances the stability of system operation and greatly reduces the power consumption of the product.

Working Principle

The ECS-120-S-28A-TR is an AT-cut crystal oscillator. It has a quartz plate as the resonator, and two electrodes connected to the quartz plate. When a constant AC voltage is applied to the electrodes, the quartz plate vibrates at a fixed frequency. The frequency of the oscillation is determined by the AT-cut technique, the size and shape of the quartz plate, and the capacitance of the electrodes. The oscillator also includes a buffer amplifier to isolate the quartz oscillator from the outside environment. The amplifier also stabilizes the frequency, so that the output frequency of the oscillator is stable.

The ECS-120-S-28A-TR is designed to operate at a frequency of 120 MHz, with a frequency tolerance of ±28ppb. This means that the frequency of the output signal will be within 28 parts per billion of the set frequency. The temperature drift of the output is also very low, which makes it ideal for applications that require a stable frequency signal over a wide temperature range.

Conclusion

The ECS-120-S-28A-TR is an AT-cut crystal oscillator that is used for frequency control of digital integration ICs and frequency modulation. It has a wide range of applications, such as wireless network synchronization, system clock modules, and lcd image stabilization control. The ECS-120-S-28A-TR has a frequency accuracy of ±28ppb, and a low temperature drift, making it suitable for applications that require a stable frequency signal over a wide temperature range.
