No traces should cross reference plane cuts within the DDR3 routing region.High-speed signal traces crossing reference plane cuts creat large return current paths which can lead to excessive crosstalk and EMI rediation.+ ]' x6 n" F2 Z& `

对其中后半句不是很理解(说高速信号线跨分割会产生大量的回流路径,这些回流路径可以导致过量的串扰和EMI辐射。) 9 m, U4 V, m6 R; Q% ^) L! {0 _' \) h4 N8 m
不知道有没有懂的人帮忙看看,简单讲讲具体的原理,谢谢! ( Z$ L* V% l! d& w' ]) | , b0 L! }* b; D% U
