1.2 TICS Pro Default Setting

The best practice when generating a new TICS Pro configuration file is to first load from a default configuration file which has been previously tested by TI. The default setting is found in the Default Configurations tab of each profile. Figure 1-3 shows the location of the default setting for the LMK5B33216 profile. Loading from the default settings allows the user to start in a known working state of register settings. After loading the default setting, complete each step in either the Start Page for LMK5B33216 or the Wizard for the LMK05318B as required for the user's application.

Make sure to calculate the DPLL loop filter register settings by clicking on the Run Script button found at the bottom of the Start Page for LMK5B33216 (see Figure 1-4) or the end of the Wizard for LMK05318B (see Figure 1-5). The MATLAB Runtime R2015b v9.0 64-bit is required and the version must match exactly to use the script.

For assistance creating a register configuration file for the LMK5B or LMK5CA family, refer to the walkthrough videos, TICS Pro LMK5Bxxxxx and LMK5CxxxxxxA profile overview and TICS Pro LMK5B/LMK5C start page tutorial. Additional videos are found in the Videos section of the TICS Pro Software website.

If the LMK device is not behaving as expected, even after using the settings generated by TICS Pro, then proceed to Debug Procedure: From Device Start-Up to Locked Output State.
