General:
Keep high-speed differential traces away from switching power supplies.
Ethernet Differential Pairs:
- Route as 100Ω differential pairs, 50Ω single-ended for other signals
- Match trace lengths within each pair
- Avoid vias and stubs in differential pairs
- Maintain a solid return path (ground plane) beneath all MDI traces
EMI/EMC Considerations:- Add TVS diodes like ESDS314DBVR on Ethernet ports for ESD protection
- Shielded Ethernet cables are recommended for noisy environments
