摘要

提出了一种自动适应任意通道阻抗和RX阻抗的FFE TX。基于片上TDR监测,在不增加反射的情况下自适应放宽TX阻抗匹配。在实验中,提出的TX适应35-75Ω通道和30-200Ω RX阻抗的任意组合,实现了3.8倍的视觉改善和12Gb/s的最大数据速率。

An FFE TX with 3.8x eye improvement by automatic impedance adaptation for universal compatibility with arbitrary channel and RX impedances
An FFE TX which automatically adapts impedance to arbitrary channel and RX impedances is proposed. Based on on-chip TDR monitoring, the TX impedance matching is adaptively relaxed without increasing reflection. In experiment, the proposed TX adapted to any combination of 35–75Ω channels and 30–200Ω RX impedances, achieving 3.8x eye improvement and the maximum data rate of 12Gb/s.
