Design Requirements

As with any high-speed design, there are many factors which influence the overall performance. The following list indicates critical areas for consideration during design.

  • Match the length between the P and N traces of the single-end segments of the differential pair.
  • Use a uniform trace width and trace spacing for differential pairs.
  • Place AC-coupling capacitors near the receiver end of each channel segment to minimize reflections.
  • AC-coupling capacitors of 220nF are recommended. Set the maximum body size to 0402 and add a cutout void on the GND plane below the landing pad of the capacitor to reduce parasitic capacitance to GND.
  • Surface mount connector is recommended. For through hole connection, back-drill connector vias and signal vias to minimize stub length.
  • Use ground reference plane vias for a low inductance path for the return current.
