I have a problem with my AD9914 Evalution Board. I used external 500 MHz for clocking AD9914 and tried to get 3.5 GHz using PLL, but in evalution software I didn't see "Lock detected" indicator.

I tried another input frequencies (400, 300, 100 MHz) from several sourses, but unsuccessfully.

When I'm using AD9914 without option "PLL enable", device works normally.
