Part Number:AM3359
The requirement was added to footnotes of each from Figure 6-2 to Figure 6-6 on the datasheet which is changed from SPRS717J to SPRS717K.
"If all the 1.8-V supplies are not sourced from the same power supply, it is required to power up VDDS before other
1.8-V supplies. Further, it is also recommended to source VDDS and VDDSHvx [x = 1-6] when configured as 1.8V
from the same power supply.
"
What problems occur if VDDS is powered up later than other 1.8-V supplies?
