Hi Rog,

These markings look correct, and it is the latest change in the product, see the issued PCN.
Here is the PCN issued regarding the marking changes.

In additional the marking changes, the FAB is changed.

The marking with 19K is manufactured in 2001 and 45M is manufactured in 2024. These are manufactured in old vs. new FABs.
These are equivalent design, but there may be some differences due to the FAB changes, which is what you observed.
If you are able to provide the schematic, I will review it and suggest modification or changes to improve the performance, if any. Please let us know.
If you do not want to post in a public forum, please post "friendship" request via E2E and we can communicate privately or via TI's internal email.
Best,
Raymond
