ACS8526T is a kind of single-chip frequency synthesizer with multiple output functions which features wide input frequency range, small package and low power consumption. It adopts CMOS process and is optimized for mobile communication applications. It can quickly frequency synthesize and output frequencies with a wide range at the same time, so it is widely applied in the communication field.

Application Field

ACS8526T finds it most application in mobile communications. It can easily output complex frequency signals and enable flexible frequency coverage. Also, it can realize the fast frequency acclimatization with GSM/UMTS/LTE multi-mode or multi-band applications. It works perfectly in the most common application on global communication frequency bands.

Working Principle

ACS8526T is based on an embedded combination of high-performance frequency synthesizers and PLLs. Its internal frequency synthesizer block works in an open-loop manner, with a high frequency resolution, which provides multiple independent output signals. It also supports multiple heterodyne-modulated output signals. With an embedded PLL, it has great stability, jitter, and fast frequency locking. The integration of PLL, multiple output functions and other optional features makes it easy to develop a powerful wireless communication application.

The working principle of ACS8526T basically includes three processes—frequency-selective mixing, frequency synthesis and frequency-locking. Frequency-selective mixing is the process of mixing incoming signal with a reference signal. This produces two intermediate frequency signals. These signals are then passed to the frequency synthesizer block, where they are used to generate multiple output signals with a wide frequency range. The last step is frequency-locking, which uses an embedded PLL to ensure that the output signal is produced with the specified frequency and phase. The PLL also helps in maintaining accuracy and preventing drift of the output signal.

Conclusion

In summary, ACS8526T is a single-chip frequency synthesizer with multiple output functions. It is optimized for mobile communication applications and can output frequencies with a wide range at the same time. It is based on an embedded combination of frequency synthesizers and PLLs, and its working principle involves frequency-selective mixing, frequency synthesis and frequency-locking. With its flexible and efficient design, ACS8526T is undoubtedly an excellent solution for wireless communication applications.
