LMX2571 Lock Problem with MULT Setting

LMX2571: LMX2571 Lock Problem

Other Parts Discussed in Thread: PLLATINUMSIM-SW, CODELOADER, TICSPRO-SW

I'm unable to get my EVK to lock on a custom frequency- screen shot below. I'm looking for guidance to set the loop filter characteristics- where can I look? I've seen in other posts a Bode plot tool, but none seems to be available in code loader 4.

Thank you!

    Mark,

    I don't see your screenshot, but for bode plots and much more I highly recommend the PLLatinum Sim tool at:

    ti.com/tool/PLLatinumSim-SW

    Also, we are transitioning from CodeLoader to TICSPro.  TICSPro is available at:

    ti.com/tool/TICSPro-SW

    Regards,

    Dean
