Noise Coupling Avoidance
Keep critical traces away from other signal traces or unrelated power
traces/areas or power supply components
Notes:
1.
Up to 4 signal vias can share a single GND return via
2.
If routing to device includes a flex or 2nd PCB, the max trace and skew calculations must include all the PCBs/flex routing
