Electrical characteristics
Table 31.
1. Take care of using the appropriate division factor M to obtain the specified PLL input clock values. The M
2. Guaranteed by design, not tested in production.
3. The use of 2 PLLs in parallel could degraded the Jitter up to +30%.
4. Based on characterization, not tested in production.
