Table 30.
1. TBD stands for “to be defined”.
2. Take care of using the appropriate division factor M to have the specified PLL input clock values.
3. Guaranteed by design, not tested in production.
4. The use of 2 PLLs in parallel could degraded the Jitter up to +30%.
5. Value given with main PLL running.
6. Based on characterization, not tested in production.
