Design Guidelines

6.1.2
General Guidelines
•
Keep traces as short as possible.
•
Traces should be routed over full solid reference plans.
•
Sensitive lines like reset and clocks should be routed with special care.
These lines should be routed over full solid power plans (ground or power).
Traces should be routed at least 2 times the trace width away from other lines in the same routing layer.
Place a series resistor ~30 ohm at the clock source.
•
Keep digital signals away from the analog side.
6.1.3
WHDI Lines
•
Place series resistors on all output lines (near the outputs pins).
•
Series resistors on input lines are unnecessary. (The series resistors should be placed on the interface
board.)
6.1.4
Power and Ground
•
Use a solid ground plan.
•
Ground plans separation is unnecessary.
•
Place decoupling capacitors near power pins. (Refer to the schematics and BOM for recommended values.)
•
Analog power pins should be filtered with ferrite beads. (Refer to the schematics and BOM for recommended
values.)
•
Add as many ground vias as possible, for better ground connections between layers and better heat
dissipation.
6.2 RF Design Recommendation
6.2.1
RF Components
All passive components must have compatible performance with components used in the Amimon reference
design.
6.2.2
Power Management
The RF power rail 3.3V_RAIL is separated from the digital power rail 3.3 with ferrite bead.
