ALEXANDRIA, Va., Dec. 23 -- United States Patent no. 12,506,485, issued on Dec. 23, was assigned to NXP B.V. (Eindhoven, Netherlands).
"Dual mode PLL for phase coherent application" was invented by Philippe Christian Belin (Mezidon Vallee d'Auge, France), Laurent Gambus (Cuverville, France) and Mathieu Perin (Cairon, France).
According to the abstract* released by the U.S. Patent & Trademark Office: "A method of operation for a dual mode Phase-Locked Loop (PLL) for phase coherent application includes selecting one of a non-coherent mode and a coherent mode. The non-coherent mode includes controlling a Voltage Controlled Oscillator (VCO) with a first error voltage determined by a first Low Pass Filter (LPF), the first LPF configured to fil...
