layers with USB 2.0 traces as much as practical. It is preferable to change layers
to avoid crossing a plane split. USB 2.0 traces as much as practical. It is
preferable to change layers to avoid crossing a plane split.
ƒ Separate signal traces into similar categories, and route similar signal traces
together (such as routing differential pairs together).
ƒ Keep USB 2.0 signals clear of the core logic set. High current transients are
produced during internal state transitions and can be very difficult to filter out.
3.5 DDI
The COM Express Types 6 Module uses Digital Display Interfaces (DDI) to provide
DisplayPort, HDMI/DVI, and SDVO interfaces. Type 6 Modules can contain up to 3 DDIs
of which DDI 1~3 can support DisplayPort, HDMI/DVI and DDI 1 can support DisplayPort,
HDMI/DVI, and SDVO. Please note that the SDVO is only supported on DDI 1 for Type 6
Modules.
