  • Patent number: 12288583
    Abstract: A method for calibrating a data reception window includes: (A) setting a level of a reference voltage by different predetermined values and repeatedly sampling a data signal to obtain multiple first valid data reception windows; (B) establishing a first eye diagram based on the first valid data reception windows; (C) resetting the level of the reference voltage by the predetermined values combined with a first offset and repeatedly sampling the data signal according to the reference voltage to obtain multiple second valid data reception windows and (D) selectively updating the first eye diagram according to the second valid data reception windows. When width of a second valid data reception window is greater than width of a first valid data reception window corresponding to the same predetermined value, the first valid data reception window in the first eye diagram is replaced by the second valid data reception window.
