General PCB Layout Recommendations For USB Mass Storage Designs
The following recommendations must be followed to ensure
reliable high-performance operation:
Use at least a four-layer, impedance controlled board to
maintain signal quality.
Specify specific impedance targets (ask your board vendor
what they can achieve).
Maintain uniform trace widths and trace spacing to control
impedance.
Minimize reflected signals by avoiding using stubs and vias.
Connect the USB connector shell and signal ground as near
to the USB connector as possible.
Use bypass/flyback capacitors on VBUS near the
connector.
Keep DPLUS and DMINUS trace lengths to within 2 mm of
each other in length, with a 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.
Do not place vias on the DPLUS or DMINUS trace routing
for a more stable design.
Isolate the DPLUS and DMINUS traces from all other signal
traces by no less than 10 mm.
