| The AD1953 has the DACs built into the DSP core, so you must choose an interpolation filter for the output. To use Output blocks with the AD1953 you will need to add an algorithm. As shown below, right-click the block to select which interpolating filter you would like to implement in the DSP core.\\ | The AD1953 has the DACs built into the DSP core, so you must choose an interpolation filter for the output.
