【应用笔记】高速通道设计的过孔优化技巧(Via Optimization Techniques for High-Speed Channel Designs)
本应用介绍高速通道设计的过孔优化技巧。
As more designs move toward high-speed serial links with picosecond
edge rates, any impedance discontinuity in the channel can adversely
affect signal quality. Channel discontinuities come from several sources
and each source must be carefully considered. One commonly
overlooked source of channel discontinuity is the signal via. Vias can add
jitter and reduce eye openings that can cause data misinterpretation by
the receiver. Via Optimization Techniques
