AD9516 reference spurs

Dear All,

I am using the AD9516-0 to clock the AD9122.

  • reference frequency = 122.88MHz
  • DAC sampling = 983.04MHz
  • PFD frequency = 61.44MHz

Around the 983.04MHz, I can observe a lot of spurs every 61.44MHz.

What is the maximum reference spurious level for the AD9516?

Thank you
