Programmable Oscillators - SIT1602BIT2-25S Application Field and Working Principle

Oscillators play an important role in application fields such as telecom and industrial automation. In this article, we discuss a specific programmable oscillator, SIT1602BIT2-25S and its application field and working principle.SIT1602BIT2-25S is a programmable oscillator developed by the company Sitronix. It is a low cost, fully-programmable, asynchronous frequency synthesizer, which is ideal for mobile communication applications. The programmable oscillator is suitable for applications such as WLANs, femtocells, smart metres, and automotive electronics. The oscillator is designed to have low power consumption, small size, low jitter, and superior signal purity across a wide frequency range. This allows the oscillator to optimize its signal path design to ensure maximum accuracy and ensure signal quality.The working principle of SIT1602BIT2-25S is based on a patented ‘Phase Locked Loop’ (PLL) technology. The oscillator uses an onboard clock and a reference clock to generate a signal frequency that is in sync with the reference clock. The output signal frequency is independent of the clock source frequency, allowing it to work well with a wide range of different clock sources. The oscillator has two main components: the programmable PLL and the dividers. The dividerscomprise of two registers which output two control signals, which regulate the frequency of the output signal. The first register holds the PLL settings, while the second register holds the divider settings. These settings allow the user to adjust the frequency of the output signal according to their specific requirements. The divide ratio of the first register should be set depending on the desired frequency of the output signal, while the second register should be set to the desired range. The oscillator can be programmed to operate at different frequencies depending on temperature and voltage. Temperature compensation registers can be used to ensure that the oscillator operates at a consistent frequency across different environments. Additionally, by changing the divide ration, users can finely tune the oscillators frequency to meet specific needs.Thus, SIT1602BIT2-25S is a versatile programmable oscillator that offers a great deal of versatility, both in terms of frequency range and accuracy. The oscillator can be used in a wide range of applications, such as WLANs, femtocells, smart metres, and automotive electronics. Furthermore, it is capable of providing accurate clock signals, even in fluctuating environmental conditions. Lastly, the oscillator is also capable of being programmed to meet specific needs.
