The NBC12429FA is a clock generator and phase-locked loop (PLL) frequency synthesizer used in a variety of communication, automation and industrial applications. The device is designed to provide a precise and reliable clock signal to replace multiple frequency sources or components, providing higher accuracy, greater system stability and saving board space, power and cost. It provides fine adjustment and flexibility to improve system timing accuracy and frequency range.

Application Field

The NBC12429FA enables the development of robust and cost-effective solutions for specialized applications in communication, industrial automation and automotive, providing ultra-low phase noise and high-stability clock outputs for a wide range of differential clocks and oscillators. It provides a stable reference clock for a multitude of devices, such as frequency synthesizers, phase shift keyers and digital signal processing components. It features programmable PLL-based output frequency from 200MHz to 3GHz, with a maximum output jitter of 50ps. Its adjustable loop bandwidth and ultra-low jitter facilitate wider frequency ranges and high clock accuracy. The device is used in a variety of applications such as clock distribution, media and storage, image and sound processing, data acquisition and switching.

Working Principle

The NBC12429FA clock generator consists of a voltage or current controlled oscillator (VCO or ICO) and a phase frequency detector (PFD). The device integrates a VCO with a programmably adjustable frequency up to 3GHz and a PFD circuit with the ability to synthesize frequencies up to 1GHz. The VCO output is divided by a programmable frequency divider and fed back to the PFD. The loop adjusts the VCO frequency until it matches the divided output frequency, effectively locking the VCO frequency to the desired output frequency. The PFD monitors the VCO output and feeds an error signal back to the VCO, allowing the clock generator to dynamically adjust the VCO frequency to track changes in the clock reference. The VCO can also be programmed to adjust its frequency offset to compensate for temperature, voltage and process variations.

The device also incorporates a reference oscillator (RC) to generate a high-accuracy reference clock frequency. This allows the use of a reference signal as low as 0.5Vpp, greatly reducing power consumption while offering exceptional performance up to 3GHz. The reference oscillator is designed to improve signal integrity and reduce system noise, providing a low-jitter and noise-free signal for high-precision timing applications.

Conclusion

The NBC12429FA makes it easy for designers to create a wide range of systems requiring precision and high speed. Its low jitter, high-stability clock outputs, wide frequency range and adjustable loop bandwidth make it an ideal device for many applications requiring accurate timing and improved signal integrity. Its programmable PLL-based output frequency up to 3GHz and ultra-low phase noise make it an excellent choice for specialized communications, automation and industrial applications.
