3.2.1 Requirements

Match the PCB line impedances to their corresponding driver impedances to reduce line reflections:

  • Single-ended lines should have a 50 Ω +/-10% single-ended impedance.
  • USB lines should have a 90 Ω +/-15% differential impedance.
  • MIPI, LVDS, DDR CLOCK and STROBE signals should have a 100 Ω +/-10% differential impedance.
