CC3301: CC3301 Recommended Power Supply

Part Number: CC3301
Other Parts Discussed in Thread: TPS65220,


The CC3301 EVM uses linear regulators to produce 1.8 and 3.3V.  I do not see a requirement in the datasheet for supply ripple.  Also, there is no indication if the chip has built in linear regulators.  I intend to combine this chip with the AM64x and its accompanying PMIC (TPS65220).  May I power the CC3301 with buck regulators already on my board or does it require clean power from a linear regulator?
