Hi Eben,

Thank you for your answer.

Today ,I just got the idea,and I thought I got the way to slove this problem.

Now,I have a new idea,I want the DAC38RF89 worked at the LMFS=82380,

So ,I can put a complex baseband data of 8 lanes to the DAC,and get the MSPS of 3333 .

Can you give me a .cfg file?

Best wishes

Xuan

Hi Xuan,

Please download the DAC GUI from here: www.ti.com/.../slac722
If you do not have an EVM, you can run the GUI in simulation mode and dump the register configuration to a file. See EVM users guide, section 3 for more details: www.ti.com/.../slau671a.pdf

Thanks,
Eben.

Dear Eben,

Thanks very much.

But ,If I want to use the wide-duc mode of LMFSHd=82380,The DAC GUI did not give this mode through the tab of 'Quick Start' .Dose The dac38rf8 can support the mode of LMFSHd=82380?

Best wishes.
