Place C near pin-B R89 is used forinternal testpurpose only. Lane 6 can be connected to LAN or Slot 5 dependingon the stuffing option described below. S4i0i Placement is such that a Capacitor can be placed there. This approach issame for RX Path also. Use type and over20 mils trace width onboth side. Close s40iu Pin 5 Close to Pin mA R is only used for RTLC application.
Use a40ii routing with 7 mil spacing. Route external layer with solid GND reference no split planes. Exs 25 mil separation from any other signal. These nets have large voltage swings.
