NB2308AC1DR2G

The NB2308AC1DR2G clock generator, also known as a phase-locked loop (PLL), is a frequency synthesizer composed of a low noise charge pump, voltage-controlled oscillator (VCO), and integrated loop filter. It is used to convert a high-frequency external reference clock (from a crystal oscillator) into a wide range of output frequencies.

The NB2308AC1DR2G is designed for use in a variety of applications that require a highly stable frequency from the output clock. These applications can include high-speed communication systems such as frequency-division multiplexing (FDM) and time-division multiplexing (TDM) systems, digital signal processing (DSP) systems, digital transmission systems, and digital image processing systems.

The NB2308AC1DR2G clock generator works by receiving a reference clock from an external crystal oscillator or other source. This reference clock acts as the input to the PLL, which is composed of the VCO, the charge pump, and the loop filter. The VCO generates an output clock at a frequency that is determined by the amount of charge pumped into the loop filter by the charge pump. The charge pump and the loop filter form a closed feedback loop with the VCO, and both adjust the output clock frequency as it changes in response to the charge applied. This closed loop arrangement allows the NB2308AC1DR2G to generate highly stable and accurate output clock frequencies.

The NB2308AC1DR2G clock generator has a range of output frequencies that spans from 0.1 to 600 MHz, allowing it to be used for many different applications. It features a fast settling time of less than 20 µs and a wide power supply range of 1.3 to 3.3 V, making it ideal for a variety of applications. It also offers a wide range of features, such as a low power consumption, a multiphase output, a locking detect output, and spread spectrum clock generation.

The NB2308AC1DR2G clock generator is designed for robust operation in a variety of applications, such as telecommunications and data communication systems, digital electronic circuits, and industrial control systems. It is also suitable for use in automotive and aerospace applications, and has been certified for use in harsh environments.

In conclusion, the NB2308AC1DR2G is an ideal choice for a wide range of clock generating and frequency synthesizing applications. Its high performance, wide range of output frequencies, and multitude of features make it an excellent solution for a variety of applications.
