AD9914 Phase Noise

We are using AD9914 and found some strange problem. At 500 MHz output phase noise is degraded by around 8 dB compare to 500.1 MHz output. 

We are using REF_CLK 3500 MHz but we have some spurious in REF_CLK at 3000 and 4000 MHz around 60 dBc down. Is it because of spurs or something else.
