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 .
