→Ethernet design rules
*For Ethernet data lines: TX differential lines (ETN_TXN and ETN_TXP) and RX differential lines (ETN_RXN and ETN_RXP)
**Equal length and symmetric with regards of shape, length, and via count.
**Maintain 100 ohm 100R differential impedance in the layout traces.
**Isolate differential pairs from nearby signals and circuitry to maintain the signal integrity.
*Among PHY vendors, the 25mm rule is considered good design practice for EMI considerations. The intention is to isolate the PHY from the magnetics.
