Finally, 5P49V5901B649NLGI8 is an ideal choice for clock generation and synchronization in industrial automation systems.

Working Principle

The 5P49V5901B649NLGI8 is a device designed to generate a wide range of frequencies with high accuracy and reliability. It works by using a Frequency Lock Loop (FLL) system based on a phase locked loop (PLL) principle. The FLL system consists of two main parts: a voltage-controlled oscillator (VCO) and a phase/frequency detector (PFD). The VCO is used to generate a clock signal of the desired frequency and a reference signal. The reference signal is compared with the clock signal by the PFD. If the two signals are not in phase, an error signal will be generated and fed to the VCO. This error signal will adjust the frequency of the clock signal and align the two signals. As a result, the clock signal will have the same frequency and phase as the reference signal.

In addition, the 5P49V5901B649NLGI8 also contains a fractional-N frequency synthesizer to allow for precise frequency setting. The fractional-N frequency synthesizer works by modulating the reference signal with a series of pulses that are in phase with each other. When the pulses reach the VCO, they will adjust the frequency of the reference signal. By adjusting the frequency of the pulses, the frequency of the reference signal can be accurately controlled.

Performance

The 5P49V5901B649NLGI8 offers excellent performance in terms of both accuracy and stability. It has an adjustable frequency range of 100 kHz to 400 MHz and a frequency resolution of 0.1 Hz. The phase noise of the clock signal is less than -85 dBc/ Hz at a frequency offset of 10 kHz. The jitter of the clock signal is below 10 ps RMS. In addition, the device has a fast locking time of less than 15 μs. Furthermore, it has an excellent temperature stability of ± 25 PPM over a temperature range of -20°C to + 70°C.

Conclusion

The 5P49V5901B649NLGI8 is a clock generator with wide application area and excellent performance. It is commonly used for a variety of applications, such as communications, broadcasting, instrumentation, embedded systems, and industrial automation. It has a wide frequency range and a high accuracy of frequency setting due to its FLL system and fractional-N frequency synthesizer. It also has excellent phase noise, jitter, and temperature stability. Thus, 5P49V5901B649NLGI8 is an ideal choice for a clock generator in many applications.
