Part Number: LMK05028

Hi, Team,

We are trying to make "2Loop TCXO APLL" DCO mode configuration, but there is a run script error.

Could you please check the attached tcs file? Please let me know the misconfiguration points.

LMK05028 Configuration.tcs

Best Regards,

  • Hello Yone-san,

    I have confirmed the error is associated with the selection of DPLL# Mode = 2 loop: TCXO, APLL.  Other modes work fine.

    I will continue to investigate find the root cause and the solution or bug-fix.
