oscillating output AD5721R

Hi everybody,

i've a problem with an AD5721R controlled by an FPGA. When I update the output from input register (i'm trying to have a continuous voltage) the output starts to oscillate.

In the attached file there's a print from scope where i've setted the DAC to generate a 5VDC (Blue channel)

 

Any help will be welcome,

Jack
