AD9912 Residual Phase Noise and Crossing Spurs

What is the residual phase noise at 200 MHz output. I can anti RSS the Wenzel noise and the absolute phase noise, but I would like the true residual noise. Also, what is the worst case crossing spur? For example if the DDS is 200.01 MHz, 4X = 800.04 MHz which mixes with 1 GHz clock to produce a spur at 199.96 MHz, or 50 KHz away from the desired signal.
