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
• For every signal line trace width (w), separate
• Maintain the same number of vias on each

traces at >2 widths from all signal line traces.
