18.2.3 Crystal Routing

The following are the recommendations for a better design with respect to trace routing to crystal.

Keep the traces from the IC pad to the crystal as short as possible.
Place guard ground vias all along the trace routed to crystal.
Surround the area around the crystal with ground polygon pour and place sufficient ground vias in this polygon pour.
