Eye-pattern design for high-speed differential links using extended passive equalization

Abstract

The performance of current high-speed consumer electronic systems is often compromised by degradation caused by distortion in eye patterns. This paper proposes a systematic method that uses the voltage transfer function for arbitrary source and load terminations to improve the eye patterns of high-speed differential links with passive components that minimize distortion. This approach is cost-effective since it only utilizes commercially available surface-mount components. The methodology has been validated by measurements in this paper.
