Hello,

Yes, RSTN does not need to be pulled high, it can be connected to ground with a 100nF capacitor.

Yes, correct. Beneath the TUSB211A, the DP/DM lanes should be shorted across these pins, as the TUSB211A does not actually carry the signal through the device.

Otherwise, schematic looks good.

Thanks,

Ryan

Thank you ,Sir

The TUSB211A (D1P/D2P) is direction-independent, right?
The D1P can be connected to a USB connector or a SoC, right?

Hello,

Yes, correct, the TUSB211A is direction agnostic. Just ensure that the D1/2P pins connect to the DP lane.

Thanks,

Ryan
