I'd like to use the AD9516 mounted on the EVB as the clock source for AD9788.
What is the requirements on reference clock input on J1 SMA connector? I'm using a 5MHz sinusoidal signal from an OCXO, but the PLL lock detect is not stable.
Is AD9516 configured in Dual Single-Ended or Differential reference mode? In Single-Ended mode I have to use a frequency greater than 20MHz, as per AD9516 specifications.
What should be the level of input reference at the SMA J1 connector? I'm using around 1.5Vpp.
