Application: Maintaining phase coherence for a fractional-n pll (Patent ID: US20240187005A1)
The patent filed by Silicon Laboratories Inc. describes a fractional-N phase-locked loop (PLL) system that maintains phase coherence for an output signal with multiple possible frequencies. The system includes an oscillator, a phase detector, a multi-modulus divider, and a multi-modulus pattern generator to achieve frequency changes in the output signal. The pattern generator initiates the drive pattern at a boundary time to ensure a repeatable phase when switching between different output frequencies. The system is designed to have a known and repeatable phase for all output frequencies, with the boundary time interval being a predetermined number of cycles of the reference clock signal.
Furthermore, the patent outlines a method for generating an output signal using the described PLL system. The method involves supplying a drive pattern to the multi-modulus divider to change the frequency of the output signal and initiating the drive pattern at a boundary time for a repeatable phase when switching between different output frequencies. The drive pattern is generated using a sigma delta modulator and is designed to have a ones density to achieve the desired output frequency. Additionally, the method involves resetting state variables of the sigma delta modulator and determining the boundary time based on the reference clock signal. The system and method ensure a known and repeatable phase for all output frequencies, making it suitable for applications requiring precise frequency control.
