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 >2 widths 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–.
