摘要

针对高速背板数据通信中的码间干扰问题，提出了多抽头决策反馈均衡(DFE)方法。开发了一个MATLAB程序来优化给定背板通道的DFE分接系数。采用0.18 /spl mu/m CMOS技术实现的带有可选模拟预均衡器的多分接DFE接收器在34”FR4背板上使用PRBS15数据实现了8gb /s的操作。

Design and optimization of multi-tap DFE for high-speed backplane data communications

Multi-tap decision-feedback-equalization (DFE) is proposed to counteract inter-symbol interference (ISI) in high-speed backplane data communications. A MATLAB program has been developed to optimize the DFE tap coefficients for a given backplane channel. A multi-tap DFE receiver with an optional analog pre-equalizer implemented in 0.18 /spl mu/m CMOS technology demonstrates 8 Gb/s operation with PRBS15 data over a 34" FR4 backplane.
