RTS5420 - Component needed in custom carrier board?

I am looking into designing a custom Jetson AGX Orin custom carrier board. Looking into the schematics (P3737) I am seeing the utilization of the RTS5420. Is this chip recommended for a custom design? I want to also have access to the 4 USBAs that the Jetson carrier board has.
Would not using this component affect in any way the USB Type C PD Controller and/or the Button Power MCU the carrier board uses, as if they are dependant of it in any way?

Hi,

If you are designing a custom base board, then it means some adaptation configurations are needed.
Otherwise, your board may not work fine.

For Orin AGX series, you could refer to below document
https://docs.nvidia.com/jetson/archives/r36.3/DeveloperGuide/HR/JetsonModuleAdaptationAndBringUp/JetsonAgxOrinSeries.html?highlight=universal%20serial%20bus#jetson-agx-orin-platform-adaptation-and-bring-up
(please be aware that above link is for rel-36.3/jetpack6.0)

This document includes below configuration

  1. pinmux change & GPIO configuration
  2. EEPROM change as most custom boards do not have an EEPROM on it.
  3. Kernel porting
  4. PCIe configuration
  5. USB configuration
  6. MGBE configuration
  7. RGMII configuration

Thanks!

Thanks for the reply.

Looking into what you have sent, the Jetson Orin is verified for only 3 USB ports, but supposedly can support up to 4. Not counting the two USB-C ports there are only two left. Leaving one for the USB-hub controller (RTS5420) and one more for the M.2 KEY E. Even if I don’t use the M.2 key, I will have only two available. Since I intend to use all 4 I will need the hub.
