In recent years, the development of technology has been rapid, and the application field of the NB2870ASNR2G Clock/Timing – Clock Generators, PLLs, Frequency Synthesizers has become increasingly wide. It is mainly used in automotive electronics, entertainment systems, computers, and communication equipment.

The NB2870ASNR2G integrates a 1.8 GHz PLL, a voltage-controlled oscillator (VCO), a phase frequency detector (PFD) and other related components together in a 3x3mm package, creating a single chip frequency synthesizer. It supports a wide frequency range from 500MHz to 1.8GHz, with a low temperature coefficient, low power consumption and high operating temperature range, which makes it suitable for a variety of applications. This device features low jitter, low noise, and excellent phase noise characteristics, enabling it to be used in applications requiring high performance.

The architecture of the NB2870ASNR2G consists of two main parts, the main path and the feedback path. The main path is composed of a PFD, a VCO, and a prescaler, which are all controlled by differential signals. The PFD receives the reference frequency and the output of the VCO, compares them, and outputs a frequency error signal. This signal control the voltage of the VCO, which is used to generate an output frequency that is close to the reference frequency. The prescaler is used to divide the output frequency of the VCO so that the output frequency is close to the required output frequency.

The feedback path is composed of a main divider, a reference divider and a loop filter. The main divider divides the output of the VCO, and the reference divider divides the reference frequency, so that the ratio between them can be proportional to the output frequency. The loop filter filters the output from the PFD and provides a DC bias to control the VCO.

The NB2870ASNR2G is particularly suitable for automotive electronics. It has low power consumption, high frequency stability and low jitter, making it suitable for advanced automotive functions such as ECUs, infotainment systems and ADAS applications. It is also suitable for entertainment systems, computers, and communication equipment, as these involve high-speed data processing and transmission, and require a stable frequency.

In a nutshell, the NB2870ASNR2G Clock/Timing – Clock Generators, PLLs, Frequency Synthesizers has a wide range of applications, is cost effective and has excellent performance. It is the ideal product for a variety of applications, due to its low power consumption, high frequency stability and low jitter, making it suitable for a variety of applications such as automotive electronics, entertainment systems, computers, and communication equipment.
