PRODUCTION DATA.
This example shows the most typical usage. One single supply, shared between all three supply voltage inputs. Rail-connected decoupling capacitors are not shown. Figure 70 shows 3.3-V supply for all supplies. Figure 71 shows separate 3.3 V for AVDD and DVDD.
NOTE
There is no disadvantage in separating the AVDD and DVDD, as the device waits until both are present before powering up.
