Figure 4. Circuit Design
The circuit design in Figure 4 shows the power connections for the power supply: the 3.3V to VDDI/O is the only input power
source and the 2.5V at VDDRCV, pin 38, is the output of the voltage regulator that needs to supply through the rest of the 2.5V
VDD pins via the 2.5V power plane.
