The NB2308AI2DT is a clock generator, phase-locked loop (PLL), and frequency synthesizer. It is all-in-one solution for a variety of purposes, and is useful for both new designs and replacing existing solutions. As the part is surface-mountable, it is a great choice for space-constrained designs, and its use of low power makes it suitable even for battery-powered designs.

Applications
The NB2308AI2DT is a great choice for many kinds of generate clock signals. The system can generate up to 8 discrete clocks at frequencies up to 400MHz, which makes it suitable for many kinds of digital designs, including microcontroller and FPGA designs. It is also suitable for use as a jitter attenuator in communications systems, providing a stable data clock that can make sure a system’s data transmission is reliable and accurate. The NB2308AI2DT is further useful for video output applications, providing a stable and low-noise clock for video sources.

Working Principle
The NB2308AI2DT uses a voltage controlled oscillator (VCO) and dividers to generate a wide range of frequencies from a given reference clock input. A PLL is used to adjust the VCO frequency, allowing the output frequencies to be locked to the reference input. The system allows for up to eight discrete outputs, each capable of up to 175MHz, and the outputs can range from a fraction of Hertz to 4GHz. The PLL is further capable of frequency multiplication to increase its range of output frequencies.

The differential output stage of the NB2308AI2DT includes a differential amplifier, allowing for impressive performance regarding control over frequency and level of the output signals. It also includes adjustable output delays, allowing for skewed clock signals to be generated, which can be helpful for designs that require such skewed signals.

The NB2308AI2DT allows for output enable/disable and power-down control, making it a great choice for designs that need good dynamic control over their clock signals. The system also supports pin-strapping mode, making it easier to get it up and running quickly and with minimal effort.

In short, the NB2308AI2DT is an all-in-one clock solution, offering a wide range of capabilities, notable performance, and low power consumption. It is a great solution for many kinds of clock generation applications, making it a great choice for new and existing designs.
