AD9915 DAC Output Currents

Looking at the AD9915 data sheet, I've a couple of queries regarding the DAC current outputs:

 

Setting the value of Iout to 20mA maximum using the recommended Rset of 3k3, is Iout the same as Ifs on Figure 26, or is it the actual current potentially available at the output pins 41 and 42, or is it the current generated by the current switch arrays (and therefore shared between the internal 50 ohm and output pin)?

Unless I've missed it, the data sheet is not too clear on this point.

 

Thanks.
