Crystals play an important role in providing timing reference signals to hardware-controlled systems. The ATS147 is a temperature-compensated crystal oscillator (TCXO) based on a quartz oscillator circuit, which is widely used in various applications such as mobile communications and network equipment. This article will discuss the application fields and working principle of the ATS147.

Application Fields of ATS147

The ATS147 is an ultra-stable and low-noise TCXO based on temperature compensating quartz oscillators. It offers excellent temperature characteristics and stability, making it suitable for a variety of applications.

In the cellular communications industry, the ATS147 is widely used in the key communication components of the base stations, providing a stable communication frequency which can be used to ensure the high-speed and errorless performance of mobile communication networks.

The ATS147 is also suitable for use in other communication applications such as pulse generators for wideband communications systems, high-end navigation systems, multi-channel navigation satellite systems, GPS receivers, and wireless local area networks.

The ATS147\'s excellent temperature and frequency stability ensures that it is suitable for use in medical instrumentation and industrial automation systems, as well as in high-end portable device applications such as personal digital assistants and handheld game consoles, which require crystal oscillator-based timing signals.

Working Principle of ATS147

The ATS147 is a temperature-compensated quartz oscillator that consists of a quartz crystal, oscillator circuit, temperature-compensated capacitors, and temperature sensors. The quartz crystal forms the core of the oscillator circuit; when an alternating current of a certain frequency is applied, the crystal vibrates, allowing the oscillator to produce a stable and accurate output signal. The temperature sensors constantly monitor the device environment and the temperature-compensated capacitors correct the frequency of the crystal. Thanks to these elements, the ATS147 is able to remain stable and accurate even in changing temperature conditions.

The ATS147 also employs a dual-mode circuit to further reduce noise which can impact the accuracy of the crystal. One of these modes is a high-precision auto-gain control circuit, which can adjust the output amplitude of the oscillator. The other mode is a low-noise phase-locked loop (PLL) circuit, which can reduce the noise produced by crystal oscillators.

The combination of these two modes ensures that the ATS147 produces ultra-low noise signals with excellent frequency stability and accuracy. This makes it ideal for use in a variety of clock signal generation applications.

Conclusion

The ATS147 is a highly reliable and accurate temperature-compensated quartz oscillator that is suitable for use in a wide range of applications. It has excellent temperature stability and low-noise characteristics, making it ideal for use in mobile communications and other communication systems, medical instrumentation, industrial automation, and portable devices.

The ATS147 also employs dual-mode circuitry to further reduce noise and increase its stability and accuracy. Thanks to these capabilities, the ATS147 is an excellent choice for clock signal generation and other timing applications.
