AD9681 balun stage

Dear ADI engineers, 

I am using AD9681. 

The balun stage in AD9681 is MABA-007159-000000 with the frequency region 4.5-3000MHz.

I would like to work with lower frequency. Could I change this balun stage to another one?

If possible. Could you recommend me some options? 

Thank you very much,

  • Hi Hoang,

    In SPIController, you can read and write FPGA registers.

    In the SPIController GUI, use the menu to navigate Config --> Controller Dialog. Then in the Controller Dialog, under "FIFO Chip Sel #" you can select FPGA. Then the register reads and writes in the GENERIC READ/WRITE window will be to the FPGA.

    You normally do not need to change FPGA registers to capture data from AD9681. Reprogramming the FPGA and changing register values could cause unpredictable behavior. Proceed with caution and at your own risk.
