The product offers excellent performance parameters for applications such as broadcasting, telecommunications, and even embedded devices. In this article, we will look at the application field and working principle of the 844251BGI-15LFT clock generator.

Application Field

The 844251BGI-15LFT was designed to meet a variety of clock/timing needs, with features such as low power consumption, low noise and jitter generation, and excellent frequency accuracy. The product is designed to be used in broadcasting, aerospace, automotive, and telecom applications, making it an attractive option for manufacturers and users. It is also used in embedded systems, such as in cell phones, wearables, digital cameras, and other mobile devices. In addition, the 844251BGI-15LFT can be used in various digital video and audio applications such as video streaming, IPTV, and digital signage.

Working Principle

The 844251BGI-15LFT clock generator is based on a Phase-Locked Loop (PLL) architecture. The PLL is a circuit used to match the frequency of an oscillator to an input signal. The 844251BGI-15LFT uses this technology to generate accurate clock signals with very low noise and jitter. It can generate clock speeds up to 130MHz with ±0.5PPM accuracy, making it an ideal choice for a variety of applications.

The 844251BGI-15LFT also functions as a frequency synthesizer, meaning that it can synthesize frequencies from a wide range of input frequencies. This is achieved by mixing two signals inside the PLL, one from the input device and one from the internal oscillator. The frequencies of the two signals are combined and the resulting output frequency is then sent out. This output frequency can be programmed using the on-board programming interface.

The 844251BGI-15LFT clocks generator also features built-in features such as programmable slew rate and spread spectrum technology. The slew rate adjusts the frequency of the output signal, which can be used to improve the jitter and reduce the noise in the signal. Spread spectrum technology allows the frequency to be spread out across different ranges, which can help improve the accuracy of the output signal.

Conclusion

The 844251BGI-15LFT clock generator is an excellent choice for a variety of clock/timing applications. The product offers excellent performance parameters, low power consumption, and low noise and jitter generation. In addition, the product is capable of generating frequencies up to 130MHz with ±0.5PPM accuracy. It is also capable of functioning as a frequency synthesizer, and includes built-in features such as programmable slew rate and spread spectrum technology. All these features make the 844251BGI-15LFT a good choice for clock/timing applications.
