NB3N1900KMNTXG Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers Application Field and Working Principle.

The NB3N1900KMNTXG is an integrated clock generator and PLL (phaselocked loop) IC that enables high precision clock and frequencysynthesis. It offers a wide range of features, including programmableoutput frequency, low skew clock output jitter, low powerconsumption, and a wide input frequency range. With this, it is ableto provide a precise clock signal even when there are changes in theinput frequency.

The NB3N1900KMNTXG is designed for use in a variety of applicationsthat require precision timing, such as telecommunications,networking, and embedded system designs. It can be used to convertan input signal into a highly precise output clock signal, providingaccurate clock jitter and frequency synthesis with minimal skew.

The NB3N1900KMNTXG integrates multiple components, including aPLL, oscillator, and programmable frequency synthesizer, into a singleIC. The PLL enables the device to accurately lock an input signal toa precise frequency, where the oscillator is used for frequencyreferencing and the programmable frequency synthesizer is used forgenerating an output clock with different frequencies from the sameinput signal.

The PLL comprises multiple pins for input and output as well ascontrol and monitoring. The input pins are used for supplying areference clock signal, which is compared to the oscillator output.The output pins are used for generating the output clock at adesired frequency. The control and monitoring pins are used tomanage the PLL, detect faults, and monitor performance.

The NB3N1900KMNTXG supports up to 4 input frequencies and 8 outputfrequencies. It also offers several modes of frequency synthesis,including Frequency Locked Loop, Digitally Controlled Oscillator(DCO), and Continuous Frequency Modulation (CFM). With CFM, theoutput frequency can be adjusted with a resolution as small as2.5ppm.

In addition, the NB3N1900KMNTXG has several features forimprovement of system performance. Its low power consumption helps toextend battery life, while its spread spectrum clock output helpsreduce EMI interference. It also includes a wide temperature rangefor reliable performance in harsh environments and a wide supplyvoltage range for accommodating various designs.

The NB3N1900KMNTXG is a versatile and reliable IC for achievingprecision clock and frequency synthesis. It features a wide inputfrequency range, low power consumption, and several modes of frequencysynthesis. It is ideal for applications that require the highestlevel of accuracy and reliability.
