The XR81411TR-F is a new generation of fully integrated frequency synthesisers with low jitter and wide frequency range. It is a dedicated Fractional-N PLL clock generator which can automatically produce many different output signals from a single input clockThe XR81411TR-F is used to generate multiple output clocks from a single input clock. It can generate clock from a fraction of the input frequency up to the same frequency as the input clock. The high frequency output clock (HFCLK) has an oscillator, divider, and phase detector built in, allowing for the generation of up to 4 output clocks, each of which has an adjustable frequency range and jitter. Additionally, the XR81411TR-F has an integral low frequency clock (LFCLK) generator with an adjustable frequency range, which can synthesise output frequencies down to 10kHz.The XR81411TR-F was designed to provide high performance with low power consumption, making it an ideal choice for many consumer electronics, telecommunications, and industrial applications. The low power consumption and wide frequency range of the XR81411TR-F make it especially attractive for use in robotic systems, IoT applications, and embedded systems where precision and accuracy are essential. The XR81411TR-F also has a low jitter condition, which allows the stable and accurate timing of output signals over a range of conditions.The XR81411TR-F has a modular and programmable architecture, allowing for easy integration with existing systems, and a wide range of user-programmable features that can be used to tailor the features of the clock generator to a user\'s specific application. The XR81411TR-F is able to support a variety of clock inputs, from quartz crystal resonators, to digital input sources such as pulse-width modulation (PWM). Combining this with the broad range of adjustable output frequencies of the XR81411TR-F allows for the easily customisation of any given signal frequency.The working principle behind the XR81411TR-F is a fractional-N phase-locked loop (PLL). The fractional-N PLL is a type of frequency synthesizer in which the output frequency is adjustable, over a wide range, in tiny increments. The fractional-N PLL uses the input clock signal to create an output signal at a fraction of the input frequency, in the same way that a normal PLL would use the input signal to generate a signal at the same frequency. The difference is that the fractional-N PLL allows for very precise adjustments to the output frequency\'s phase, so that a range of frequencies can be produced using the same reference clock. The frequency of the output signal is adjusted by altering the controller\'s settings, by altering the "divide-by-N" setting, or by changing the charge pump current. The accuracy and stability of the output signal is dependent upon the accuracy and stability of the input clock signal. The XR81411TR-F also uses dithering and noise shaping techniques to further improve the clock generator\'s accuracy and stability.The XR81411TR-F can be used in a variety of applications, from clock generators in telecom and network equipment, to industrial automation and robotics, to time management and instrumentation applications. This versatile clock generator is able to meet the needs of a wide range of applications due to its low power consumption, adjustable clock frequency range, and integrated low frequency clock generator. As such, the XR81411TR-F has become an increasingly popular choice for portable applications, where accuracy and low power consumption are essential.
