2.3.1.6 Terminations

  • DMD_HS differential signals require no external termination resistors.
  • Make sure the DMD_LS_CLK and DMD_LS_WDATA signal paths include a 43-Ω series termination resistor located as close as possible to the corresponding controller pins.
  • Make sure the DMD_LS_RDATA signal path includes a 43-Ω series termination resistor located as close as possible to the corresponding DMD pin.
  • The DMD_DEN_ARSTZ pin requires no series resistor.
