USB Type C super-speed routing doubts

[Anonymous]

Hi All

I have designed a USB - USB type C receptacle pass-through board. I have started routing the 90R controlled impedance tracks for the USB. I've got the information from the manufacturer to use a trace width of 0.22mm and trace spacing of 0.125mm to achieve 90R impedance. I heard D1_P and D1_N needs to be short to enable the flipping feature. It is a four layer board. I am attaching the schematic and board layout.  Could anyone guide/help me with the layout? Is that correct?

Thanks

 Are you sure the facility for checking the diff pairs length is working in V7? I don't see any list underneath.

No sorry I forgot to consider v7 as I have been using v8 and v9 so long now.

Maybe a good reason to upgrade?

Makes sense now. Probably time to upgrade. 

Thanks for all.

This product will probably work better by incorporating a USB re-driver with support for USB 3.1 Gen 1 (5GBps) & Gen 2 (10Gbps) like this one:

This will alleviate issues with having to use shorter cable length and user confusion when links fail.

Yes, it's already implemented. Anyway thanks for your advice

Great! Which re-driver did you use?

Sorry, that is done by a contractor as I don't have much information about it.
