LMK04832: LMK04832:configure the lmk04832 with the data from the tics pro,but it doesn't work

Part Number: LMK04832

Hello:

I met some problems I can't sovle.

I use the Tics pro software to generate the register data as the above pictures showed,then I export the register data to a txt file. Then I use the SPI port to transfer the data to LMK04832 in order showed in txt file.I am sure the data is correctly configured to LMK04832,because I can read the LMK04832 register data from the SPI port and the reading data is what I transfer to it.But to my surprise, the LMK04832 can't work,some channels have no clock out and some channels have the wrong clocks,for example,13.5MHz clock. No matter how I change the N divider number or other number, the result is the same. So I really don't know what to do next and where I am wrong, I sincerely hope your help, thank you!

  • Hi Wang,

    Can you share the Tics Pro file, which you are using to program the LMK device?

    While seeing the images, it seems you have mentioned VCO frequency is 2048MHz. LMK04832 is not supporting this frequency range.

    Are you using LMK04832EVM or LMK device on your board? If your board, what is the programming connector option you have on board?
