USB3.0 Layout Guidelines:
1. USB3.0 Differential trace impedance: 90ohm
2. Differential pairs The USB3.0 the total trace skew less than 5 mils.
3. IC pad to USB Connector total length < 4"(Max)
4. USB3.0 Capacitor 0.1u_10V_X7R_04 Close to Connector.
5. PCIe Differential impedance 85 ohm.
6. PCIe For transmitter and receiver the total trace length: 1"(Min)~~6"(Max).
7. PCIe Number of vias 4via hole(Max).
8. PCIe clock Differential impedance 100 ohm.
9. PCIe Differential pairs and pairs spacing 20mils, with Other trace spacing 25mils.
10. Power Trace width=20mils, Spacing=80 mils.
