The NB6N239SMNR2 is an advanced clock generator product which was developed to meet the demanding needs for high speed and precision in today\'s market. It is designed to be used in a variety of systems in which accurate timing signals are critical to proper operation, such as Ethernet and 4G/LTE communication systems, as well as analog signal conditioning and audio/video applications.

The NB6N239SMNR2 is a low noise, digitally-controlled, frequency modulated oscillator (DCO) capable of generating high-quality output clock signals from 0.25MHz to 212MHz. It features a wide variety of output types, including various CMOS, LVDS, LVPECL, and HCSL outputs, allowing it to be used in a variety of applications. The oscillator also offers internal high-frequency synthesizer PLL (Phase Locked Loop) capability, allowing it to be easily combined with other clock sources, thus, permitting the generation of complex frequencies in a simple fashion.

At the heart of the NB6N239SMNR2 is a high-performance frequency modulated (FM) oscillator which is capable of providing extremely precise output frequencies. The frequency of the FM oscillator is determined by two external resistors, Rx and Ry, and a third adjustable voltage, Vfreq. The Rx resistor determines the frequency at which the oscillator will oscillate, while Ry sets the slope of the frequency versus voltage curve. The adjustable Vfreq control voltage allows for fine tuning of the output frequency, and is also used to enable the internal PLL.

The NB6N239SMNR2 has two built-in fractional-N divides which can be used to select the output frequency from a wide range of available frequencies. High resolution frequency division can also be achieved by using the internal Digital Frequency Stimulator (DFS) feature. In this mode, the desired output frequency is set by writing a 32-bit control word to the device, allowing for resolution to better than 1Hz.

For additional flexibility, the NB6N239SMNR2 also has an integrated clock adjustment pin which can be used to fine-tune the phase and frequency of the output signal, allowing the user to make very precise adjustments to the output signal. To maintain high output signal quality, the device also features a low-jitter, phase-locked loop (PLL) which can lock the output signal to an external reference signal.

For applications that require an even more precise frequency control, the NB6N239SMNR2 also supports an optional external clock input which can be used to precisely control the output frequency. When used in conjunction with the internal PLL, this feature allows for even more precise frequency control and jitter reduction.

In summary, the NB6N239SMNR2 is a high performance, low noise, digitally-controlled, frequency modulated oscillator perfectly suited for use in applications where accuracy and precision timing are essential. Its wide range of output types, adjustable frequency control, and built-in fractional divider and PLL make it an ideal choice for many demanding applications.
