7.2.1 Layout Guidelines
Use the following guidelines to lay out the CC2650MODA device:
- The module must be placed close to the edge of the PCB.
- TI recommends leaving copper clearance on all PCB layers underneath the antenna area, as shown in Figure 7-2 and Figure 7-3.
- TI recommends using a generous amount of ground vias to stitch together the ground planes on different layers. Several ground vias should be placed close to the exposed ground pads of the module.
- No external decoupling is required.
- The reset line should have an external pullup resistor unless the line is actively driven. Placement of this component is not critical.
- TI recommends leaving a clearance in the top-side copper plane underneath the RF test pads.
