Enhanced eye-height estimation of mismatched lossy transmission lines

A simple formula is derived to estimate the worst-case eye height for mismatched transmission line systems, using system pulse response and the idea of peak distortion analysis. A contour map which represents eye height variations for different reflection coefficients at the drivers and receivers is constructed and used to facilitate the driver and termination designs for the best eye diagram performance. Subsequently, the eye diagram results for two different mismatched transmission lines are given to validate the accuracy of the presented contour map.
