LMK5B12204: LMK5B12204 Technical assistance

Part Number: LMK5B12204

Hello
     I want to use this clock chip LMK5B12204 quickly. I have read all the data and found that this chip can not only use FPGA and MCU configuration register to achieve the required output clock frequency. It can also be configured with the upper TICS Pro and downloaded to the eeprom inside the LMK5B12204 chip.
     I want to make sure that this is as I understand it; If so, could you please provide me with relevant downloaders and DEMO boards? Borrow or buy my side can be!

    hello,
      I use LMK5B12204, and the register configuration information generated by TICS Pro is 411, while the register mapping table provided by the data manual is 261. May I ask how can I get the clock output I need?

      As shown in the following picture

    Hello,

           I have encountered many problems since debugging LMK5B12204. 1. The register list exported by TICS Pro software does not match the specification. 2, I use the exported register data to send to the chip through SPI, the chip still does not work, did not achieve the expected effect. 3. How high is the SPI communication rate? I understand the pattern according to the timing diagram. There is no clear explanation in the specification. Is the register list wrong? Or the rest of the questions. I read all the information no less than 10 times, still a little confused; I beg your company to help configure a usable tcs script for me, so that I can change it. Otherwise this is too much work!
