In the process of high-speed and high-density PCB design, crosstalk interference should be especially focused since it greatly affects timing and signal integrity. Some design solutions are given. First, the continuity and matching of the routing characteristic impedance should be controlled. Second, spacing should be noticed and spacing is normally twice line width. Third, proper termination methods should be picked up. Fourth, routing in adjacent layers should be implemented in different directions. Fifth, blind/buried vias can be used to increase routing area. In addition, differential termination and common-mode termination should be maintained so as to reduce the influence on timing and signal integrity
