8.4.1.5 PCB Layer Stacking

To meet signal integrity and performance requirements, at minimum a 4-layer PCB can be used. However a 6-

layer board is recommended. See Figure 8-12 for the recommended layer stack ups for 4, 6 and 8-layer boards.

These are recommendations not requirements, other configurations can be used as per system requirements.

Figure 8-12. Recommended Layer Stack Up

Within a PCB, a desirabled can be to run traces using different methods, microstrip vs. stripline, depending on

the location of the signal on the PCB. For example, the opportunity can be desirable to change layer stacking

where an isolated chassis ground plane is used. Figure 8-13 illustrates alternative PCB stacking options.
