Product Number: ADRV9029
Hello,
I am currently working with the ADRV9029 evaluation board.
I would like to be able to switch dynamically between LO1 and LO2 on Rx3.
I found the following code lines in the DLL Help section of the TES:
initStruct.clocks.rx12LoSelect = Types.adi_adrv9010_LoSel_e.ADI_ADRV9010_LOSEL_LO1
initStruct.clocks.rx34LoSelect = Types.adi_adrv9010_LoSel_e.ADI_ADRV9010_LOSEL_LO2
initStruct.clocks.tx12LoSelect = Types.adi_adrv9010_LoSel_e.ADI_ADRV9010_LOSEL_LO1
initStruct.clocks.tx34LoSelect = Types.adi_adrv9010_LoSel_e.ADI_ADRV9010_LOSEL_LO2
However, these settings are intended for the initialization procedure and not for dynamic switching during runtime.
I also found the function LoSourceMappingSet, which should allow me to map LO1 and LO2 to Rx3 as described below:
rxPllMappingMask | Channel PLL Source Mapping
---------------------|------------------------------------
bit[0] | 1 = Rx12 to LO2, 0 = Rx12 to LO1
bit[1] | 1 = Rx34 to LO2, 0 = Rx34 to LO1
Unfortunately, I am facing a roadblock. I am unable to make my IronPython code run correctly on the ADRV9029 board using TES. I keep receiving the following error:
System.Exception: ERROR 9025 does not support adi_adrv9025_LoSourceMappingSet ...
Does this error mean that the LoSourceMappingSet function cannot be used with the ADRV9029?
My questions are:
- Is it possible with this chip to switch from LO1 to LO2 for a specific Rx or Tx channel after the initialization and calibration procedures are complete?
- If yes, what is the procedure? I assume I should follow the "CALIBRATION GUIDELINES AFTER PLL FREQUENCY CHANGES" section in UG-1727.
- If LO switching is possible after initialization, do you have an example of IronPython code that could help me use the
LoSourceMappingSetfunction correctly?
Best regards,
François
