PCB LAYOUT GUIDELINES
Electrical Layout Considerations
Implementing a high speed USB device requires paying
attention on USB lines and traces to preserve signal
integrity. The demonstration board serves as a layout
example and can support the design engineers to preserve
high speed performances.
Electrical layout guidelines are:
The bypass capacitor must be placed as close as
possible to the V
CC
input pin for noise immunity.
The characteristic impedance of each High Speed USB
segment must be 45 W.
The ground plane of the PCB will be used to determine
the characteristic impedance of each line.
All corresponding D+ / D line segment pairs must be
the same length.
The use of vias to route these signals should be avoided
when possible.
The use of turns or bends to route these signal should
be avoided when possible.
