13. PCB Layout Recommendations

Follow these recommendations to ensure reliable high perfor- mance operation:[24]

■Four layer impedance controlled boards are required to maintain signal quality.

■Specify impedance targets (ask your board vendor what they can achieve).

■To control impedance, maintain trace widths and trace spacing.

■Minimize stubs to minimize reflected signals.

■Connections between the USB connector shell and signal ground must be near the USB connector.

■Bypass and flyback caps on VBus, near connector, are recom- mended.

■DPLUS and DMINUS trace lengths should be kept to within 2 mm of each other in length, with preferred length of 20 to

30 mm.

■Maintain a solid ground plane under the DPLUS and DMINUS traces. Do not allow the plane to split under these traces.

■Do not place vias on the DPLUS or DMINUS trace routing.

■Isolate the DPLUS and DMINUS traces from all other signal traces by no less than 10 mm.
