Dear team,

can you please specify where in the datasheet is the PLL lock time specified?

Thanks,

    Peter,

    Thanks for posting the question! I am in the process of checking with our experts that were intimately involved with the PLL investigation and any subsequent actions. I will let you know as soon as I get the full picture on where and how this is documented.

    Peter,

    I have done some digging on this and the documentation of the lock time is included in the TRMs. Unfortunately, we are still in the process of updating all of our TRMs for this paramater and the TMS570LS3137 TRM, SPNU499, is not yet updated. Below is the updated lock time formula that will be changed in the applicable TRM and has already been added to most other TRMs.
