Re: AD9548 DPLL is not locked
Hello Ignat, The frequency lock and phase lock circuits are for monitoring only, and are independent. Were you not able to achieve phase lock by using R0x0600<7>=1? As I said before the lock...

Also, the ASRCs will do a lot of the "cleaning" for you, I think. They take an asynchronous input and re-time, or re-synchronize it to an internal reference clock.
