Set ADRV9026 AUX LO Frequency Failed

Thread Summary

The user encountered an error when setting the AUX LO frequency to 2.6GHz using adi_adrv9025_PllFrequencySet(). The solution is to use the default AUX LO frequency for initial calibrations and change it afterward. The AUX LO can be set independently of the Tx PLL, with special requirements handled using adi_adrv9025_PllFrequencySet_v2().

Hi Team:

    When I call the adi_adrv9025_PllFrequencySet() to set the AUX LO frequency, the issue as bellow:

    1.Set 1.6GHz,it is OK;

    2.Set 2.6GHz,the fail info:

    CpuCmdStatusWait() failed due to thrown CPU error. Is device in correct state for calling command? 
    file:public/src/adi_adrv9025_cpu.c, func:adi_adrv9025_CpuCmdStatusWait(), line:1056 
    ADRV9025 CPU Command Error
 
    TxQECDrv:NCO synchronization timed-out

    adi_adrv9025_PllFrequencySet fail 

    Are there any differences in configuration between AUX and PLL1/2?

    Is AUX LO truly independent?not bound to TX PLL?

    Looking forward to your reply!

    Thanks!
