Super Speed Type-C Connectors

In this layout example a dual row SMT mid mount Type-C connector is used. Start by placing vias for all the signals on the Type-C connector that need to be routed on another layer. Once the vias have been placed, route out the super speed lines and place their ESD protection close to the Type-C connector. The figures below show the via placement, top routing, and bottom routing for the super speed signals on the Type-C connector. The same should be implemented for both Type-C connectors.
