In one of our custom Board, RF loopback is not passing, Cna you tell me how to debug this?
TX NCO tone can be seen out of DAC. PLL is also locked.

Hi Vijay ,
Its passing now . the error is in the LMK locking . Its showing lock and AFE is also showing lock. But if you see the DAC output its clear that clocks are not Phase locked properly. By changing the LMK CPLL2 filter value its solved.
Thanks for the help
