Use controlled-impedance PC board traces to match the cable characteristic impedance. The termination resistor is also matched to this
Eliminate reflections and ensure that noise couples as common mode by running the differential traces near each other.
Reduce skew by using matched trace lengths. Tight skew control is required to minimize emissions and proper data recovery of the devices.
Route each channel’s differential signals very close to each other for optimal cancellation of their respective external magnetic fields. Use a
Avoid 90° turns (use two 45° turns).
Minimize the number of vias to further prevent impedance irregularities.
