TBD stands for “to be defined”.

Take care of using the appropriate division factor M to have the specified PLL input clock values.

Guaranteed by design, not tested in production.

Maximum input PLL frequency is recommended for applications sensitive of long term jitter.

Value given with main PLL running.

Based on characterization, not tested in production.
