通过低成本底板进行高速电子数据传输是一个特别具有挑战性的问题。我们首次提出了一种非常有效的方法，它使用双二进制信令的概念来完成这一任务。使用有限脉冲响应滤波器，我们能够补偿背板的相位和幅度响应，从而得到的通道的频率响应是理想的双二进制滤波器的频率响应。在背板的输出端，我们使用了一种创新的伪数字电路来将电气双二进制转换为二进制。对于10 Gb/S数据传输，我们在FR4上展示了通过电底板跟踪长度高达34英寸的误码率<；10/sup-13/。对该系统的概念、系统结构和测试结果进行了全面的讨论。分析了这种方法与PAM-4和标准不归零信令的比较和对比。
High-speed electrical data transmission through low-cost backplanes is a particularly challenging problem. We present for the first time a very effective approach that uses the concept of duobinary signaling to accomplish this task. Using a finite-impulse-response filter, we are able to compensate for the phase and amplitude response of the backplane such that the resulting frequency response of the channel is that of an ideal duobinary filter. At the output of the backplane, we use an innovative pseudodigital circuit to convert the electrical duobinary to binary. For 10-Gb/s data transmission, we demonstrate a bit error rate <10/sup -13/ through electrical backplane traces up to 34 in in length on FR4. A full discussion of the concept, system architecture, and measured results are presented. Analysis is presented that compares and contrasts this approach to PAM-4 and standard nonreturn-to-zero signaling.
