Hi,
Could you give some comments for below TUSB7430's applicaiton questios from our customer? Thanks,
--------
1. We found the differential pairs is not convenient for us to routing when we do the layout work. So we want to swap the positive signals and negative signals of the receive differential pair.
I check the datasheet and found the chip has swap function, so it's OK for hardware to swap them. But I heard there is firmware to drive the chip, so I want to know if I swapped the signals, need I change something in my firmware?
2. Also about the differential pairs swap, the differential clock and the differential signal seems swapped in the application of datasheet. Is it just convenient for routing or anything else? I want to know the reason why you swapped those signals in application of datasheet.
Thanks.
Best Regards,

Hi JMMN,
The information I found in the datasheet you provided about the allowable differential pair swapping for the TUS7340 device is showed in the picture.
Can I understand as I need to change nothing in my firmware if I swapped the positive signals and negative signals of the receive differential pair?
