The XR81101-AA02-F device is a circuit intended for use in applications such as clock, timing, frequency synthesis and other applications that require a programmable frequency clock source. It is a frequency source generator (FSG) and is ideal for applications in which high accuracy and stability are required. This device is manufactured using advanced CMOS processes and features a programmable output frequency and duty cycle, low noise, and power efficient design. The device is very useful for use in synchronous and asynchronous systems.

The XR81101-AA02-F is capable of generating a wide range of frequency outputs with a very low spectral noise. It has built-in programmable frequency dividers, so that users can easily set the desired frequency with high accuracy. The device also has a built-in phase-locked loop (PLL), which allows it to operate even more accurately and generate more precise clock signals. This device also has a PLL-compatible input, allowing it to lock on to external signals for further stability of the frequency output.

The major application field of the XR81101-AA02-F is in clock and timing applications, such as frequency synthesis and system synchronization. It can be used to generate the frequency clock signals required for communication and digital logic systems. It can also be used to provide synchronization and jitter reduction for digital audio systems, such as audio/video capture cards, audio mixing boards and digital synthesizers.

The working principle of the XR81101-AA02-F is based on the utilization of a phase-locked loop (PLL). The circuit contains a voltage controlled oscillator (VCO) and a pair of dividers. The dividers divide the output of the VCO into two signals which are applied to the inputs of a phase comparator. The phase comparator measures the phase difference between the two divided signals and produces an error signal. This error signal is used by the PLL to adjust the frequency of the VCO, enabling the PLL to track the frequency of the input signal and thus generate the desired output frequency.

The XR81101-AA02-F has two programmable output frequencies, one of which is the main output frequency, and the other is a fraction of the main frequency. The main output frequency can be programmed in steps of 0.01Hz, while the fractional output can be programmed in steps of 0.1mHz. The device also has a programmable duty cycle and a programmable reset delay.

The XR81101-AA02-F is a very flexible and accurate clock generator that is ideal for applications requiring precise and stable frequency clocks. It is designed to meet the most demanding requirements of digital communication, clock and timing systems, frequency synthesis, and other applications. The device is manufactured using advanced CMOS processes and is highly power efficient, making it well suited for battery-powered applications.
