I am implementing a USB to UART conversion board with a FT232RQ. What confuses me is the fact that the USB_D+ and USB_D- pins of the package are sequenced in precisely the opposite order as they are on any USB connector.
What options do I have to properly route the USB traces? I have come up with the following but I am not really satisfied with any. On the other hand I am at most a beginner so your hints might help clarifying the issue.
- use a through-hole USB connector and place the FT232RQ on the opposite side to the connector such that the traces go straight
- use a SMD connector and place the FT232RQ on the opposite side, but route the traces through vias
- place the components on the same side and do some crazy trace gymnastics (having to match their length).
Additionally, being a quad-flat package, there is no possibility of routing the USB traces "under" the package.
Is this even a "real" problem? The confusion might be fully due to my lack of experience in the field.
Thanks you!
