  • Reference voltage calibration using a qualified weighted average
    Patent number: 10515028
    Abstract: An apparatus and method for encoding data are disclosed that may allow for performing periodic calibration operations on a communication link. A controller may determine multiple possible values for a reference voltage used with the communication link based on an initial value. Calibration operations may be performed using each possible value, and the results of the operations scored based on the width of data eyes measured during the calibration operations. The controller may then select a new value for the reference voltage from the multiple possible values dependent upon the scores of each of the multiple possible values.
    Type: Grant
    Filed: July 9, 2018
    Date of Patent: December 24, 2019
    Assignee: Apple Inc.
