Hi! NXP Engineer
Is Ground*RX_P/N = "RX_P and RX_N pins are connected to Ground" in i.MX 8M Plus Hardware Developer’s Guide?
Thanks a lot
The same as above in i.MX 8M Plus Applications Processor Datasheet for Consumer Products.
Solved! Go to Solution.
Hi @www1519,
Unused signal termination is recommended to follow for:
1. Noise immunity
2. To reduce additional power consumption.

Hi Mr.Ritesh M Patel@riteshmpatel
I see. Thank you.
But according to ds, if USB1 or USB2 or USB1&2 do not used, USBx_RX_P and USBx_RX_N should be connected to the Ground.
If USB1 & USB2 are used as USB 2.0(not USB 3.0), USBx_RX_P and USBx_RX_N should be connected to the Ground? or be floating?
(I think USBx_RX_P and USBx_RX_N are used for USB 3.0)
Hi @www1519,
If USB 2.0 connections are only used, USBx_RX_P and USBx_RX_N should be connected to the Ground.

→I see.Thank you.
If They are not connected to the GND, and only power consumption of SoC is increasing, is correct?

Hi @www1519,
I hope you are doing well.
