The 5P49V5913B507NLGI8 clock/timing generator, synthesizer, or phase-locked loop (PLL) is used for a multitude of applications, most notably that of frequency control. It enables highly integrated systems, with very low phase jitter and extremely high frequency stability.

Application Areas

The 5P49V5913B507NLGI8 clock generator, synthesizer, or PLL is utilized in applications that require highly accurate and stable frequency outputs. These include such applications as satellite ground station, fiber networks, cable TV, GPS, and cell phone base stations. Additionally, they are used to generate highly accurate and stable clocks that are prerequisites in demanding embedded applications such as set-top boxes, high-end video recorders, telecom, and data acquisition systems.

The 5P49V5913B507NLGI8 clock/timing generator, synthesizer, or PLL is also widely used in the computing industry, where highly accurate and stable frequencies are required for system clock synchronization and clocking systems, such as DDR and GDDR memory, PCIe interfaces, and RAID controllers. Additionally, it is ideal for automotive applications, as it provides vibration tolerance and even-temperature performance, which is particularly important in the harsh automotive environment.

Working Principle

The 5P49V5913B507NLGI8 clock/timing generator, synthesizer, or PLL utilizes a fractional-N or integer-N programmable frequency synthesizer. Essentially, this means that the output frequency can be programmed to any frequency within the given limit, with fractions of a Hertz accuracy. The PLL core sustains a constant reference frequency over a variety of temperature, supply voltage and loading conditions.

How this works is that the reference oscillator circuit receives an external frequency reference; this external reference can be pretty much any frequency, depending on the application. The reference oscillator circuit then generates an internal reference frequency according to the set input reference frequency. The generated internal reference frequency is then compared with a feedback signal from the voltage-controlled oscillator (VCO). In this way, the feedback signal is blanked and synchronized with the reference frequency. This PLL loop has very low phase jitter and can provide a very stable output clock or PLL.

Advantages

The 5P49V5913B507NLGI8 clock/timing generator, synthesizer, or PLL has a number of advantages compared to other similar devices. One of the most important advantages is its high accuracy and stability, which make it an ideal choice for many applications. Additionally, its flexible design allows for very high input and output frequencies, allowing it to be used in a wide range of applications. Finally, its low power consumption, small size, and integrated function capabilities give it a competitive edge in space-constrained applications.

Disadvantages

As with any electronic circuit, the 5P49V5913B507NLGI8 clock/timing generator, synthesizer, or PLL also has some disadvantages.
