An oscillator is a device or system that generates oscillatory signals. Oscillators produce waveforms of many different shapes, and are used for a wide variety of applications. The AX7DCF4-480.0000C oscillator is a commonly used oscillator, used for its good characteristics in terms of stability, ruggedness and price. In this article, we will discuss the AX7DCF4-480.0000C oscillator application field and working principle.

Application Field

The AX7DCF4-480.0000C oscillator is a low power device that offers excellent stability, ruggedness, and price for a variety of applications. It is widely used in communication, instrumentation, monitoring, and control systems. The oscillator can be used in access systems, such as digital terrestrial television (DTT) or digital video broadcasting (DVB), where it provides the basic clock signal for digital sampling. In addition to the common frequency of 48MHz, the AX7DCF4-480.0000C oscillator can also be used for other frequencies such as 40MHz, 5.5MHz, or even 4.4MHz.

The oscillator is also frequently used in wireless communication applications. It is often used for frequency selection in radio transceivers, such as Wi-Fi radios, GPS transceivers or radio modems. Additionally, the AX7DCF4-480.0000C oscillator can also be found in automotive electronics, as it provides excellent stability and long-term reliability. This makes it well suited for automotive communications, such as tire pressure monitoring systems (TPMS) or remote keyless entry (RKE).

Working Principle

The AX7DCF4-480.0000C oscillator produces a periodic, sinusoidal output waveform at 48MHz. It uses a quartz crystal resonator as its control element, which consists of two quartz plates with metal electrodes on their surfaces. A voltage is applied across the quartz crystal, which causes its quartz plates to vibrate. This vibration produces a sinusoidal voltage signal at the resonant frequency of the quartz crystal. This signal is then amplified and filtered to create an oscillating wave at the desired frequency.

The AX7DCF4-480.0000C oscillator has two types: open loop and closed loop. The type of oscillator used depends on the application and the desired performance. The open loop type has no feedback circuit, so it can easily oscillate without a feedback signal. However, the output waveform and oscillation stability are not as good as the closed loop type. The closed loop type has a feedback loop that provides improved waveform accuracy and stability. Additionally, the loop filter can be adjusted to reduce the output voltage ripple and improve its frequency accuracy.

Conclusion

The AX7DCF4-480.0000C oscillator is a versatile and reliable oscillator, suitable for a wide range of applications. It has good stability and ruggedness, making it well suited for automotive communication systems, access systems, and wireless communication systems. It uses a quartz crystal resonator as its control element, and can be used as either an open loop or closed loop oscillator. In conclusion, the AX7DCF4-480.0000C oscillator is a great choice for many applications.
