USB Termination


Could you please advise if the iMX8QM has onboard or on chip USB2.0 termination resistors? The carrier board design guide doesn’t explicitly mention anything about terminating USB2.0; so I was wandering if we need to put any termination resistors on our carrier board.


Hi @kperu01

There are no external termination resistors required on the USB 2.0 signals. All the termination is inside the SoC. Just follow the Ixora or Apalis Evaluation Board schematics for the external components required for the USB interface.
