Currently struggling with routing differential pairs for USB Type-C female connector
Currently struggling with routing differential pairs for USB Type-C female connector in my design, and it's proving to be quite challenging, especially with issues like length matching. Do you have any tips or strategies for effectively routing these pairs while ensuring signal integrity remains intact? Because the Type C has Two Set of differential pair, dont know what to do here.

Full USB Type-C has 5 differential pairs in total. All in USB signal groups. USB 2.0 signals are to be connected at the connector and routed as a single differential pair.
Route all USB High Speed signals with 90Ω differential impedance traces without stubs. It is preferred to route these USB High Speed signals on the Top Layer with the Inner Layer 2 being a solid Ground plane as their reference. These signals should not cross a plane split. If it crosses a split it can degrade the signal.
Here a good thought out article for more information

I heard that the type C can be used for audio streaming. Have you worked on any project on that @Petr Dvořák
When speaking of type-C, it is about the physical connector. The USB3.x behind can encapsulate video streaming, audio streaming, and many kinds of data transfers, usually generic. Even the old USB 2.0 can transfer video or audio. You would not be surprised when seeing a web camera connected through USB 2.0.
No, I have never worked on any project with USB audio or video streaming.
Thanks petr
Ok
