  • Adaptive filtering for precision time protocol with physical layer support
    Patent number: 11831405
    Abstract: Systems and methods for reducing phase delay variation impact are described. A microcontroller can receive a sequence of phase offsets determined by a slave device over time. The microcontroller can determine a weight vector based on a metric associated with the sequence of phase offsets. The microcontroller can adjust a set of filter coefficients based on the weight vector. The set of filter coefficients can be filter coefficients of a filter being implemented by the slave device to filter incoming packet data.
    Type: Grant
    Filed: March 11, 2022
    Date of Patent: November 28, 2023
    Assignee: Renesas Electronics America Inc.
    Inventors: Oleksandr Korovin, Alexandru Mihut, Greg Anton Armstrong, Leonid Goldin
