Hi,
We are developing a custom carrier board with Jetson Orin NX SOM.
I have a design query with USB Implementation.
In the below attaching my method of implementation plan of USB.
In this, for Enabling the Power Switch (IC3), which pin I can use?
You can refer to the Design Guide and reference carrier P3768 schematic in DLC for USB design. And the combination should follow below items.
*) USB2 + USB3 in pair connecting to a USB HUB
*) USB2 + USB3 in pair connecting to a PD controller and then to a type-C port
*) USB2 + USB3 in pair connecting to a type-A port
Hi Trumany,
Can’t we implement the combination in the custom carrier board that’s mentioning below?
USB 0 - recovery USB (micro B Connector)
USB 1 - through MUX to type-C Port
USB 2 - to USB Hub
As said, for USBSS port, the USB2 + USB3 combination should be in pair first and then go to same port/hub together.
Hi Trumany,
Sorry I didn’t get it what you replied.
You are specifying USB 2 as USB 1 and USB 3 as USB 2 as per the image I shared. Correct ?
my doubt is, why we can’t implement the each USBs separately ?
(standalone, not using USB0 SS Signals, keeps floating)
Why we can’t implement in this way? why need to make a combination of USB 1 and USB 2?
Thank you for your support.
I mean for USB3.0 port, USB2.0 should combine with USB3.0 and go to same port or hub together.
If you use USB2.0 separately as USB2.0 port without USB3.0, that would be ok.
Ok, got it. That will be fine,
I am doing like that only.
Thank you.
