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. Also see the PCB landpattern information in this data sheet.
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.
