=== Internal / External VCC-INT DVDD Supply ===

By default the MegaRF will provide the VCC-INT DVDD supplyusing a regulator inside the MegaRF chip. If you wish to use an external supply you will have to use the VADJ setting on the CW308 to set the VCC-INT DVDD supply to be slightly higher than 1.8V, which would cause the MegaRF on-board regulator to shut down.

In our experimentation the internal VCC-INT DVDD regulator worked fairly well, and did not add significant noise to any measurements.
