US Patent Issued to Silicon Laboratories on Oct. 27 for "Maintaining phase coherence for a fractional-N PLL" (Texas Inventors)

ALEXANDRIA, Va., Oct. 27 -- United States Patent no. 12,776,781, issued on Oct. 27, was assigned to Silicon Laboratories Inc. (Austin, Texas).

"Maintaining phase coherence for a fractional-N PLL" was invented by John M. Khoury (Austin, Texas) and Michael Wu (Austin, Texas).

According to the abstract* released by the U.S. Patent & Trademark Office: "A fractional-N phase-locked loop (PLL) that maintains phase coherence for an output signal with a plurality of possible output frequencies. The fractional-N PLL includes an oscillator, a phase detector to receive a reference clock signal and a feedback signal, and a multi-modulus divider coupled in a feedback path between the oscillator and the phase detector. A multi-modulus pattern generator ...
