and power plane underneath the input pins is
recommended. For best performance, no vias should
be used in this high-speed signal path.
A large cut-out underneath the right angle BNC
connector, the AC coupling capacitors, ferrite beads
and inductor is needed for minimal parasitics.
This proposed layout is designed to be largely
independent of the used PCB-layer stack. This will
work as well for four, six or even higher numbers of
layers. Possible extra layers should have cut-outs as
large as the full proposed footprint.
