USB 3.0 standard TYPE-A receptacle traces to CYUSB3014

[Anonymous]

I design a USB 3.0 IO card with a USB 3.0 standard TYPE-A receptacle and CYUSB3014BZXI. when I route my PCB, I find the differential pairs cross each other.In AN70707,it says "The polarity can be swapped on the USB 3.0 differential pairs."，so I want build the traces(STDA_SSTX-,SSTXP),(STDA_SSTX+,SSTXM),(STDA_SSRX-,SSRXM),(STDA_SSRX+,SSRXP).it means that I swap the SSTX, don't swap the SSRX.but in DVK, cypress swaps the SSRX, doesn't swap the SSTX.

   

so please tell me, my design can work fine?

Hi,

   

You can either have TX swapped or RX swapped or both swapped. Your design will work fine.
