Abstract

A continuous-time multiple-input multiple-output crosstalk cancellation (MIMO-XTC) architecture operating at 2-6 Gb/s has been proposed. The performance of the XTC equalizer has been measured with various spacings of FR4 channels and data rates. The crosstalk energy reutilization technique efficiently handles crosstalk and achieves high signal integrity in severe crosstalk environments where crosstalk had completely closed the data eye. Measurement results show improvement in jitterp-p and vertical opening of the eye diagram by 67% UI and 58.2%, respectively, which is the best known improvement to date. The MIMO-XTC portion occupies 0.03 mm2 and consumes 2.8 mW/Gbps/lane, which is two times lower than previously proposed XTC schemes.
