I am testing LMK05318BEVM. I fed a 15MHz LVCMOS signal to PRIREF input and try to make the DPLL/APLL1/APLL2 to this reference input. However it seems the DLL always failed locking to 15MHz input. I programed the part with TICS Pro v126.96.36.199. Attached is the configuration file generated with TICS Pro. Could you please help me check what is wrong with it?
