WebMay 1, 2024 · USB High Speed Signals: Route all USB High Speed signals with 90 Ω 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 (see Figure 3). Routing USB Type-C High … WebA ground plane on a printed circuit board (PCB) is a large area or layer of copper foil connected to the circuit's ground point, usually one terminal of the power supply. It serves …
