PCB LAYOUT
The PCB and components are made of leadfree and
RoHS compliant materials. The layout is shown in Figure 5
below. The top layer traces are shown in magenta, and the
bottom layer traces are shown in cyan. Ground pours are
present on the top and bottom layers for connectivity. PCB
dimensions are 53 mm x 58 mm x 1 mm.

PCB LAYOUT GUIDELINES
Implementing a high speed USB switch device requires
paying attention on data lines and traces to preserve signal
integrity. The demonstration board serves as 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 characteristics impedance of each switch
segment must be 45 W.
The ground plane of the PCB will be used to
determine the characteristics 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.
