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.(by platform).
9.
PCIe Differential pairs and pairs spacing 20mils, with Other trace spacing 25mils.
10.
Power Trace width=20mils, Spacing=80 mils.
