NOTE
The exposed die attach pad must be connected to a solid ground plane as this is the
primary ground connection for the chip. Inductance in vias to the pad should be minimized. It
is highly recommended to follow the reference layout. Changes will alter the performance.
For best performance, minimize the length of the ground vias, by using a 4-layer PCB with
ground plane as layer 2 when CC2591 is mounted onto layer 1.
