USB3.1 Gen 2 circuitry

On the Jetson Xavier NX Developer Kit, a Cypress CYPD4226-40LQXIT microcontroller is used to control the Texas Instruments TUSB1046-DCIRNQT USB redriver.

  • Is the microcontroller strictly required?
    • Is the source code for the microcontroller available?
  • In a captive development environment where general USB functionality isn’t needed (only high speed data transfer is needed without power delivery or general USB device support), can the USB redriver be omitted from the design if short cables are used and we are willing to manually ‘flip’ the USB-C connector to correct any data line reversals?

Hi, the mcu is NOT must. For USB part design, please follow the Design Guide well. There are some examples in the doc.
