AFE5812EVM: Different GND

Part Number: AFE5812EVM

Hello TI people,

I have a question about the different ground in AFE5809/AFE5812 EVM. 

It has three ground GND(Power GND), AGND and DGND(USB). 

Now, From the schematic, I can see that Analog Ground is the Power ground. So would that be ok that if I connect AGND pins of an AFE5809/AFE5812 chip to normal ground and just keep two isolated ground on board, that will be GND and DGND. 

Thank you.
