Layout Considerations
The EVB-USB2412 is designed on four PCB layers--two signal layers and two ground layers. The PCB
layer stackup is shown in
with ground floods. Internal layers are ground. Note that the differential signals from the USB2412
match the upstream and downstream port placement simplifying the routing of the critical USB signals.
