7.3.1.2 PCB Layer Stacking
To meet signal integrity and performance requirements, at minimum a four layer PCB is recommended for
implementing PHYTER components in end user systems. The following layer stack-ups are recommended
for four, six, and eight-layer boards, although other options are possible.
Figure 7-13. PCB Stripline Layer Stacking
Within a PCB it may be desirable to run traces using different methods, microstrip vs. stripline, depending
on the location of the signal on the PCB. For example, it may be desirable to change layer stacking where
an isolated chassis ground plane is used. Figure 7-14 illustrates alternative PCB stacking options.
