Programmable oscillator is a frequency-controlled device which output frequency is determined by an internal or external reference. One of the most important products in this category is SIT3809AI-C-28NH, which has been widely used in many applications in recent years. In this article, we will discuss the application field and working principle of SIT3809AI-C-28NH.

SIT3809AI-C-28NH oscillators can be applied to a broad range of applications, suggesting a wide range of operational use cases. The SIT3809AI-C-28NH is an ideal choice for providing fast response to accurate signals which requires very precise tuning at high frequencies, such as cellular telephone base stations, RF power amplifiers, and spectrum analyzers.The ability to configure its operation for specific applications makes this device even more attractive. In addition, the oscillator is capable of working with either an internal time base or an external signal frequency standard. Finally, this device has a wide frequency range from 10 Hz to 20 GHz which allows the user to tune an oscillator to a precise frequency.

The working principle of SIT3809AI-C-28NH is quite simple. It consists of an oscillator core, a temperature controller, a programming port, and a phase-locked loop (PLL) circuitry. Firstly, a reference signal is provided to the oscillator core where it produces an oscillation frequency based on the user-defined range. This reference signal is then passed to the temperature controller which helps it to adjust the output signal frequency by controlling the temperature. The output signal is then passed to the PLL circuitry which is responsible for stabilizing the output frequency and providing the user with precise tuning.

In the PLL circuitry, the signal is compared to the reference signal which is compared to the external signal frequency standard. If the output frequency does not match with the reference signal, then the PLL circuitry adjusts the frequency and — by dint of feedback — continuously ensures that it is synchronized with the reference signal. The result is an accurately tuned and stabilized oscillator with a precise frequency.

In addition to the above mentioned application areas, SIT3809AI-C-28NH can be used in test and measurement, medical imaging, and communication systems. It is suitable in situations where a high precision and wide range of frequencies are required. Moreover, the oscillator is designed to be used in many other applications where performance, reliability and accuracy are important factors.

In conclusion, the SIT3809AI-C-28NH is one of the most user-friendly programmable oscillators available in the market, with a wide range of application areas and a continuous frequency tuning capability. Its stable and precise output frequency makes it suitable for precise signal generation applications, and its efficient and accurate temperature control makes it an ideal choice for many industrial and commercial applications.
