I have 2 questions regarding AD9162 start-up operation.
We have AD9162 in our board connected to FPGA and to Synthesizer.
1. DLL unlocked.
I followed the power-up sequence procedure in the DAC data-sheet (table 43).
I used manual start-up sequence and also ADI application. both with same DLL results.
I read register 0x92 (DLL_STATUS) and get 0x0. (DLL_FAIL=DLL_LOST=DLL_LOCKED=0).
2. DC test mode.
I activated DC test mode in ADI application. choose frequency and amplitude.
I watch the signal at the output with a spectrum analyzer and see the correct frequency but with a very low
power (-60 dbm).
