10.1 Layout Guidelines

To avoid the need for signal vias, it is highly recommend to route the High Speed traces on the same surface layer than the TUSB213 is placed. shows an example how one could layout the PCB for TUSB213.

The layout should use impedance controlled traces to maintain 90 Ω differential impedance for the whole signal path as required per USB 2.0 specification. General guidelines for highspeed signal routing apply.
