Title:
METHOD AND SYSTEM FOR OBTAINING THRESHOLD VOLTAGE OF DATA INTERFACE
Document Type and Number:
WIPO Patent Application WO/2021/004342
Kind Code:
A1
Abstract:
Disclosed in the present invention are a method and system for obtaining a threshold voltage of a data interface, relating to the technical field of communications. By scanning a signal eye pattern to extract valid voltage pairs falling within a preset range, and then computing a threshold voltage of a data interface according to the valid voltage pairs, the interference of a "top-clipped" (or "bottom-clipped") voltage pair in the signal eye pattern can be avoided, and the accuracy of a computed valid threshold voltage is ensured, so that characteristics of the data interface, such as the signal amplitude, jittering, signal sampling stability and reliability, and interfering noise resistance capability, can be more precisely learnt about, thereby performing accurate determination on data interface performance.
