Sigma DSP integer/fraction

I am trying, without success, to recover the integer/fractional parts of a sine wave multiplied by a constant. The integer part is used to index a delay buffer of 500 samples. I need the fractional part for interpolation of the output. Is this possible with Sigma DSP without losing too much resolution? (ADAU1761)
