【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.
