12.0PCB Layout Recommendations

The following recommendations must be followed to ensure reliable high-performance operation.

•At least a four-layer impedance controlled board is required to maintain signal quality.

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

•To control impedance, maintain trace widths and trace spac- ing to within specifications.

•Minimize stubs to minimize reflected signals.

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

•Bypass/flyback caps on VBus, near connector, are recom- mended.

•DPLUS and DMINUS trace lengths must be kept to within 2 mm of each other in length, with preferred length of 20–30 mm.

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

•It is preferable to have no vias placed on the DPLUS or DMINUS trace routing.

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