I Have two Ad9518's in different slots of my system that have the same 10mhz input clock in common. Both AD9518's are also configured to generate a 400Mhz clock on output 0&1. I'm trying to figure out how to phase align the outputs and I figured that since the 400Mhz was an integer multiple of the 10Mhz input the both outputs would be phase aligned. I've also tried to enable (via csr write) and toggle the external sync pin without any luck. Are there any tips to phase align the outputs?
