AD9954 output's amplitude

Hello,

 

I'm using an ad9954 in single tone mode in order to generate a sine at a determind frequency. I achieve to manage the FTW0 and output my sine but with an amplitude near than 20 mv. In page 13 of the datasheet , it's said that the compliance range of the dac output is AVDD +0.5 to AVDD-0.5V. I tryed to write in the ASF different amplitude value but that doesn't any effect on the output. Can you tell me how to manage the amplitude in single tone mode?

 

Thank you
