Component placement for this schematic page
will allow for flow thru routing of TX and RX
differential pairs on top PCB layer.
Three connector options are provided.
Only one may be mounted at a time.
The footprints are closely spaced so as to minimize trace stubs.
R58 and R96:
Place one near J1/J2/J3
Place the other nearer L1
These components are optional. They are suggested
only for applications requiring maximum noise immunity.
