    Abstract: A high-speed router backplane is disclosed. Because of the large number of high-speed conductive traces present in such a backplane, electromagnetic interference (EMI) can be a serious issue. And because such a router consumes significant amounts of power, some provision must exist (e.g., bus bars in the prior art) within the router for distributing power to the router components. In preferred embodiments, power distribution is accomplished using relatively thick (e.g., three- or four-ounce copper) power distribution planes within the same backplane used for high-speed signaling. To shield these planes from EMI, they are preferably placed near the center of the material stack, shielded from the signaling layers by adjacent digital ground planes. Also, where two power supply planes exist, the power supply planes are placed adjacent, further shielded by their respective power return planes. Each power distribution plane can also include a conductive guard ring to shield that plane from EMI injected at the board edges. And where the backplane includes both high-speed and lower speed signaling traces, at least some lower speed signaling traces are placed on signaling layers, designated as low-speed, that are closest to the power distribution planes.

    Abstract translation: 公开了一种高速路由器背板。 由于这种背板中存在大量高速导电迹线,电磁干扰(EMI)可能是一个严重的问题。 并且因为这样的路由器消耗大量的功率,所以在路由器内必须存在一些设备(例如,现有技术中的汇流条),以将功率分配给路由器组件。 在优选实施例中,使用在用于高速信号的相同底板内的相对较厚(例如,三或四盎司铜)功率分布平面来实现功率分配。 为了屏蔽这些平面与EMI,它们优选放置在材料堆叠的中心附近,通过相邻的数字接地层与信号层屏蔽。 此外,在存在两个电源平面的情况下,电源平面被放置在相邻的位置,被其各自的功率返回平面进一步屏蔽。 每个配电平面还可以包括导电保护环,以将该平面与在板边缘处注入的EMI屏蔽。 并且在背板包括高速和低速信令迹线的地方,至少一些较低速度的信令迹线被放置在最接近配电平面的信号层(被称为低速)上。
