Systems and methods for determining and compensating for differential pair pairwise time offsets

Abstract

In accordance with embodiments of the present disclosure, an information handling system may include a processor, a first information handling resource communicatively coupled to the processor, and a second information handling resource communicatively coupled to the processor and the first information handling resource. The first information handling resource and the second information handling resource may be configured to, in concert determine an optimum delay between opposite polarity signals for differential signals communicated from the first information handling resource to the second information handling resource via a path comprising a differential pair and transmit data from the first information handling resource to the second information handling resource via the path by inserting a delay into one of the opposite polarity signals equal to the optimum delay.

Description

technical field [0001] The present disclosure relates generally to information handling systems and, more particularly, to determining and compensating for time offsets in communication paths within communication path information handling systems. Background technique [0002] As the value and use of information continue to increase, individuals and businesses seek additional ways to process and store information. One option available to users is an information handling system ("information handling system"). An information handling system processes, compiles, stores and / or communicates information or data primarily for business, personal or other purposes, thereby allowing users to exploit the value of the information. Because technology and information processing needs and requirements vary between different users and applications, as to what information is processed, how information is processed, how much information is processed, stored or communicated, and how quickly ...

AI Technical Summary

Problems solved by technology

However, this approach is unlikely to eliminate all sources of pairwise time offset

For example, pairwise time offsets may be introduced by various manufacturing precision including, but not limited to, the fiberglass weave of the printed circuit board in which the component may be mounted, mismatched integrated circuit chips, mismatched printed circuit board wiring, mismatched terminal pins Matching and other processing mismatches of signal transmitter and / or receiver components
