ADRV9009 MCS and RF PLL Phase Sync Question

Hello,

    I am using custom board with ultrascale+ and muti adrv9009.

    I need to use MCS and RF PLL phase sync function.

    The software that I use is no-os example( I modified for muti chip) and Firmware is 6.0.2, API is 3.6.0.5.
   

    Refer to UG1295 and API manual,  I did some tests and got results as list:

    1. Just run TALISE_enableMultichipSync(), and .rfPllPhaseSyncMode = TAL_RFPLLMCS_INIT_AND_SYNC.

        Result : After TALISE_enableMultichipSync, I get MultiChipSyncStatus,the SyncStatus value is 0xB. Look muti TX Singal on the oscilloscope, RF PLL Phase Sync is not sync.

    2. Run TALISE_enableMultichipSync(), and set .rfPllPhaseSyncMode = TAL_RFPLLMCS_INIT_AND_SYNC.

        Result : same as test 1.

    3. Just run TALISE_enableMultichipRfLOPhaseSync(), and set .rfPllPhaseSyncMode = TAL_RFPLLMCS_INIT_AND_SYNC.

        Result : After TALISE_enableMultichipSync, I get MultiChipSyncStatus,the SyncStatus value is 0x3, JESD Link Status error.

    3.Set .rfPllPhaseSyncMode = TAL_RFPLLMCS_INIT_AND_SYNC, run TALISE_enableMultichipSync() first, then run TALISE_enableMultichipRfLOPhaseSync() , and set                          .rfPllPhaseSyncMode = TAL_RFPLLMCS_INIT_AND_SYNC.

        Result : After TALISE_enableMultichipSync, I get MultiChipSyncStatus,the SyncStatus value is 0xB, after TALISE_enableMultichipRfLOPhaseSync() , the SyncStatus value is 0x3, JESD Link Status OK, RF PLL Phase is synced.

So,

1. Should I use both TALISE_enableMultichipSync() and TALISE_enableMultichipRfLOPhaseSync() for mcs and RF PLL sync?

2. why does TALISE_enableMultichipRfLOPhaseSync() reset  Device Clock divider Sync Status? Does this have any effect to msc ?

  • Hi srimoyi,

    It's good luck to so many useful suggestions about MCS. I have a question that what does Initialize all devices in system using TALISE_initialize means?" "

    For example, I have one zcu102+two adrv9009s, does it mean that I should TALISE_initialize the first board and then the second board and then do chips MCS? like the figure below?
