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 TUSB215-Q1 is placed. shows an example how one could layout the PCB for TUSB215-Q1.

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.
