AD 9833 overclocking

Hi,

 

    We want to generate a sine waveform of around 5-10Mhz for medical applications. The board was designed by a team member using AD9833 and 50Mhz clock. Now we realize that AD9833 gives a noise prone sine wave output at frequencys greater than 3MHz and it even fails to construct a valid output at high frequencies.

 

    We do not want to redesign the board. Is it possible to over clock the AD9833? How much distortion will we get? Also are there any componet with similar footprint as AD9833 that can act as a replacement.
