ENet - Layout Guidelines:
- Trace impedance: 100 Ohm differential impedance to the
ground plane.
- Adjacent TX/RX differential pairs should be separated by
more than 15 mils to each other.
- TX/RX differential pairs should be routed on TOP or
BOTTOM layers only.
- Match trace length of differential pairs, 100 mils max within
a pair, and 500 mils max between pairs.
- Trace impedance: 100 Ohm differential impedance to the
ground plane.
- Adjacent TX/RX differential pairs should be separated by
more than 15 mils to each other.
- TX/RX differential pairs should be routed on TOP or
BOTTOM layers only.
- Match trace length of differential pairs, 100 mils max within
a pair, and 500 mils max between pairs.
