PCB Layout Recommendations
Although the USB standard and applications are not based in
an impedance controlled environment, a properly designed
PCB layout is recommended for optimal transceiver perfor-
mance. The suggested PCB layout hints are as follows:
Match signal line traces (VP/VM, D+, D–) to
40ps, approximately 1/
3 inch if possible. FR-4
PCB material propagation is about 150ps/inch,
so to minimize skew try to keep VP/VM, D+/D–
traces as short as possible.
For every signal line trace width (w), separate
the signal lines by 1.5–2 widths. Place all other
traces at >2w from all signal line traces.
Maintain the same number of vias on each
differential trace, keeping traces approximately
at same separation distance along the line.
Control signal line impedances to ±10%.
Keep R
S as close to the IC as possible, with
equal distance between R
S and the IC for both
D+ and D–.
