Board Layout
4-layer board design (Table optimized high-speed signals. board uses epoxy dielectric material with relative dielectric constant 4.9. proper design requires 14mils foil thickness each copper layer 0.1mm dielectric thickness between layers. high-speed signals routed through impedance-matched transmission lines. line width these signal lines 14mils, with ground plane height 8mils. board layout separates analog digital portions circuit. Matched impedance transmission lines used high-speed digital inputs. digital inputs arranged half circle match line lengths between inputs pattern clock generators' connectors. lengths these transmission lines matched within 50mils minimize layout-dependent data skew. Wherever large ground planes used, care taken ensure that analog planes overlap with digital planes. This eliminates possibility capacitively coupling digital noise through circuit board sensitive analog areas.
