Hello , I'm meeting a problem. I give a 65MHz diff clock to the clk+ and clk- of a AD9228, However, the Dco ,Fco have no clock output , Dco+ is 1.35V, Dco- is 1V. I don't know how to make Dco and Fco output clock. Is the Dco and Fco output clock automaticly if give the clk pin a input clock? Please help me!!!
