The 844251BGI-15LF device is a synthesizer generator that provides frequency synthesis and clocking functions in a wide range of frequency ranges and applications. It is particularly useful for providing low-jitter, high-frequency clocks in applications that are commonly used in signal processing, communications, medical, instrumentation, and control systems. It is ideal for high-speed communications between devices, such as RF modems, and for driving signal processing applications such as Digital Signal Processing (DSP) and video signal processing.

The 844251BGI-15LF device is a multiphase generator with two driven outputs. It has two input sources, which can be set to different frequencies. The frequency of the output can then be adjusted to match the frequency of the input signal. The device also incorporates a phase-locked loop (PLL), which helps to ensure that the output frequency remains in lockstep with the input signal. To help improve jitter performance, the device has four integrated voltage controlled oscillators (VCOs).

The device’s operating frequency range is from 0.1MHz to 2 GHz. This wide range makes the device suitable for use in a variety of clock and data applications. It is also suitable for use in applications that require extended temperature range and has several features that are tailored to this environment.

The 844251BGI-15LF also incorporates a closed loop time base that is designed to ensure the accuracy of the output frequency. The time base is made up of four programmable delays that can be used to accurately adjust the timing of the output signal. The device also includes an on-chip temperature compensation circuit that compensates for temperature variations and helps to maintain the accuracy of the device’s output frequency.

The 844251BGI-15LF device is also able to provide an adjustable amount of synchronization between two signals. It can also synchronize two signals of different frequencies, allowing for the application of pre-set frequencies or frequency offsets. This feature makes the device suitable for applications such as digital audio, video, and communications.

The 844251BGI-15LF is also able to provide an integrated spread spectrum clock generator (SSCG) that can be used to reduce the amount of electromagnetic interference (EMI) generated by the device. This feature is useful for applications that require low noise and high EMC performance.

The 844251BGI-15LF device is available in small surface mount packages and comes with an evaluation board, which allows designers to quickly evaluate the generator’s performance. It is also available with various software options for customizing the device’s operation, such as frequency locking and phase adjustment.

In summary, the 844251BGI-15LF is a versatile, high-performance synthesizer generator capable of providing frequency synthesis and clocking functions in a wide range of frequency ranges and applications. It provides low-jitter, high-frequency clocks and can be used in applications such as digital signal processing, RF modems, digital audio, video, and communications. It also includes features such as adjustable delays and temperature compensation that help to ensure the device’s accuracy and reliability. Finally, the device is available with a variety of software options and evaluation boards that allow designers to quickly evaluate its performance.
