AD9833 phase shift resolution 10bits or 12bits?

I'm trying to use the DDS AD9833 for a TDR application but according to the datasheet, it says, its phase shift has resolution of 12 bits

but its DAC has only 10bits?  Whats the real resolution for the phase registers?   

 

 

If this DDS does not have 12 bits phase resolution is there another DDS with 12bits  phase resolution?

 

 

I would like to phase shift my output square wave in increments of 0.1 degrees.

 

Thanks in advanced....
