AD7764 grounding in EVAL board

I would like to know what is the grounding scheme employed in the AD7764 EVAL board. Are there two different grounds employed or a single ground. The tracing on the document for EVAL board suggests that there are two different grounds but the schematic shows only one ground (at least symbol wise).

 

Further the AD7764 dataheet says to connect the AGND pins all to ground. I hope the ground refers to analog ground or is it otherwise.

 

Regards
