1. Calibrated during manufacturing tests.

2. Guaranteed by design.

3. Guaranteed by characterization results.

4. ΔfHSI = ACCHSI48_REL + ΔVDD

5. These values are obtained by using the formula: (Freq(3.6 V) − Freq(3.0 V)) / Freq(3.0 V) or (Freq(3.6 V) − Freq(1.62 V)) / Freq(1.62 V).

6. Jitter measurements are performed without clock sources activated in parallel.
