Recommended USB connector

Hi all,

 

I'm looking for recommendations for good USB connectors for a design using a Kinetis L chip (MKL27Z).

 

I'm currently basing my design on: HIROSE UX60SC-MB-5S8

I like this connector because it has large mounting holes, making it look quite sturdy.

 

However, as others have found (Routing USB to Kinetis K20: crossing traces? ) this connector and most others I've seen, you need to swap traces on the board.

D+/D- have to be swapped, and VREGIN also has to cross both data lines.

 

Can anyone recommend a good USB connector that doesn't have this issue? I am looking for mini USB, but I am also interested in micro USB for future projects.

 

Also, for traces that will be ~13cm, can someone recommend values for good trace width / trace spacing?

I used Edge Coupled Microstrip Impedance | Electronics and Electrical Engineering Tools | EEWeb Community  to calculate 0.508mm width and 0.254mm spacing would give ~140 Ohms diff impedance. (The recommend is 90 Ohms)

 

Thanks!

Joey
