The NBC12429AFNR2G is a highly integrated chip designed to optimize the performance of a wide range of clock generators, PLLs, and frequency synthesizers used in any number of commercial and industrial applications. It integrates an advanced, low-power phase-locked loop (PLL) system with a chip-to-chip oscillator, and offers a high detection range, small package size, and fast switching.

Application Field

The NBC12429AFNR2G is commonly used to generate the accurate clock signals necessary to synchronize digital devices in a variety of applications, such as computer clocks, mobile telecommunications systems, optical communications systems, television sets, and military systems. It can also be used in other high-speed applications such as data acquisition systems, motor control, automotive electronics, and instrumentation systems.

Working Principle

The NBC12429AFNR2G works on a fundamental principle of frequency synthesis. It uses a voltage-controlled crystal oscillator to generate a low-power reference frequency. This reference frequency is then multiplied or divided by a PLL to generate the desired output frequencies. This allows for high-accuracy clock signals from any input frequency. The chip also uses a fractional-N divider technique to generate low jitter frequency outputs, even in the low frequency range.

The chip also contains a slew-rate control logic, which enables more accurate synchronization of frequency and jitter. This logic also provides programmable means to reduce power consumption without sacrificing the frequency stability of the synthesized outputs. The chip also provides programmable output drivers, which can drive the output waveform into any finished circuit design.

The NBC12429AFNR2G provides a number of features to enhance its functionality. These include an auto-resume function, as well as an integrated periodic jitter attenuator for improved robustness in environments with high electrical noise. It also includes a frequency-lock indication feature, which allows the user to monitor the frequency status of the chip, and an automatic mode switch, which enables switching from low to high frequencies with the push of a button.

The NBC12429AFNR2G is a highly versatile chip and is used in many commercial and industrial applications, where accurate and stable clock signals are required. It is easy to implement and can be used for a wide range of frequencies. With its slew-rate control logic and programmable output drivers, it is also suitable for driving signals into more advanced circuits.
