PLL characteristics
Subject to general operating conditions for V
Table 24.
1. Data based on product characterisation, not tested in production.
2. Refer to jitter terminology in
3. The jitter specification holds true only up to 50mV (peak-to-peak) noise on V
4. The PLL parameters (MX1, MX0, PRESC1, PRESC2) must respect the constraints described
