XLL725266.000000I Datasheet/PDFAh, oscillators. They are one of the most essential electrical components, often used in many different applications. Today, we will be discussing the XLL725266.000000I oscillators, its application field, and its working principle. So, let’s get started.
XLL725266.000000I oscillators are mainly used in video production fields for television broadcast systems, computer video interface systems, and other application systems that require long-term, stable scanning and signal processing. The XLL725266.000000I is a PLL type oscillator with a SO-8 package that has low cost, high precision, and low jitter performance. The device consists of an oscillator dip IC, an adjustable voltage reference control IC, and a synchronization/lock circuit.
The working principle of the XLL725266.000000I oscillator is quite unique; the oscillator operates under a digital phase locked loop (DPLL) system. The system controls the output frequency by adjusting the voltage reference, thereby obtaining a buffer-driven frequency locking environment. Firstly, the oscillator input reference signal is compared to the internal reference signal and the detected difference is fed back to the oscillator as a voltage control signal. At the same time, the previous frequency is taken as an internal reference signal for the next step. This constant comparison and adjustment process becomes a repetitive cycle, thus ensuring the stability and accuracy of the voltage control.
This DPLL structure allows the oscillator to operate in a wide range of frequencies from 10MHz to 200MHz with high accuracy and low noise. The device can be easily programmed with any external control voltage. In addition, a calibration circuit is used to correct the spurious phase noise of the device while maintaining a low phase noise output.
Overall, the XLL725266.000000I oscillator offers excellent performance for video production applications. It can provide users with a stable, low-noise, and high-accuracy reference frequency signal without any manual adjustments. There are also many other advantages, such as fast response and high cost-effectiveness. For these reasons, the XLL725266.000000I oscillator is a suitable choice for some video production applications.
