8.2.1 Design Requirements
This section lists some critical areas for high speed printed circuit board design consideration and study.
- Utilize 100-Ω differential impedance traces.
- Back-drill connector vias and signal vias to minimize stub length.
- Use reference plane vias to ensure a low inductance path for the return current.
- Place AC-Coupling capacitors for the transmitter links near the receiver for that channel.
- The maximum body size for AC-coupling capacitors is 0402.
