Oscillators are an important part of electronic products, and there are many types of oscillators available on the market today. One popular type of oscillator is the ASCO-4.000MHZ-EK-T, a miniature surface mount ceramic oscillator used for frequency control of communications and digital signal processing applications. In this article, we will discuss the application field and working principle of the ASCO-4.000MHZ-EK-T oscillator.

Application Field

The ASCO-4.000MHZ-EK-T oscillator is a highly integrated, minor-package, miniature surface-mount surface-acoustic-wave (SAW) oscillator which combines a temperature compensated quartz SAW based frequency control circuit with an ASIC microprocessor, providing stable frequency control over a wide temperature range. It is suitable for use in a variety of communications and digital signal processing applications, such as telecommunications, data networking, wireless Local Area Networks (LANs), and cable networks. Its small size and low power consumption make it an ideal choice for portable applications where size and energy efficiency are critical. The oscillator can operate over a wide temperature range of -40°C to +85°C and is RoHS compliant.

Working Principle

The ASCO-4.000MHZ-EK-T oscillator operates by utilizingsurface-acoustic-wave (SAW) technology. SAW technology is a chip-based transmission system in which a quartz crystal is cut and etched with a regular oscillating pattern that creates periodic acoustic waves on the crystal\'s surface. The output of the chip is then amplified by a transistor to produce a signal with a frequency that is determined by the point on the quartz crystal at which the acoustic waves are generated. By controlling the point at which the waves are generated, the frequency of the signal can be precisely controlled within tight tolerances.

The ASCO-4.000MHZ-EK-T oscillator combines the temperature compensated quartz SAW based frequency control circuit with an on-chip ASIC microprocessor that enhances the device\'s performance. The ASIC microprocessor compensates the temperature changes and provides precise frequency control over a wide temperature range. The oscillator also features selectable output formats, allowing the user to adjust the output to the needs of the application.

In addition, the ASCO-4.000MHZ-EK-T oscillator is designed with an internal high frequency trim for highly reliable frequency stability. The trim allows the user to fine-tune the oscillator\'s frequency to the desired setting for the particular application. It also features a low frequency jitter of 0.25ps (12KHz to 40MHz), making it an ideal solution for applications that require higher frequency accuracy and stability.

The ASCO-4.000MHZ-EK-T oscillator is a versatile solution for a wide variety of applications, making it a popular choice among designers and manufacturers of communications and digital signal processing applications.
