AD5293 not responding

Hi,

 

I am trying to use an AD5293 but it doesn't seem to behave correctly.

First the RDY output pin didn't seems to toggle.

Second, I notice that the EXT_CAP pin is at 0V.

The other supply levels are fine.

 

Channel 1 is SYNC

Channel 2 is SCK

Channel 3 is RDY

 

Any clue?

 

Thanks
