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.
The setup for using the AD9788 EVB is described in the user guide and includes clocking instructions for the AD9516 in the "Using the AD9516 " section.
