SATA & USB - Layout Guidelines & Notes
1. The Dp and Dn traces are length matched, with max differential skew, within 20mils
2. Differential trace length must be less than 5 inches
3. No more than 2 vias per trace, prefer zero.
4. Never split the ground plane under differential pair routing
5. Route differential pairs above the GND plane.
6. Differential impedance is 100 Ohms for SATA and 90 ohms for USB.
7. Adjacent differential pairs should be separated by at least 3 times the trace width.
(e.g. 7.5 mil trace, leave >22.5mils between adjacent diff pairs)
8. Stich gnd vias around each differential pair, but NOT between a given pair.
9. SATA xtal +/- 50 ppm Tolerance +/- 100 ppm Stability
