38.3.3.5 Oscillator Tolerance

The oscillator tolerance, df, around the nominal frequency of the oscillator, fnom, is defined in Equation 38-6.

Equation 38-7 through Equation 38-8 describe the conditions for the maximum tolerance of the oscillator.

Equation 38-6. Oscillator Tolerance

(1 - d f) \times f n o m \leq F_{S Y S C L K} \leq (1 + d f) \times f n o m

Equation 38-7. Condition 1

d f \leq \frac{N S J W}{2 \times 10 \times \frac{N B T}{N T Q}}

Equation 38-8. Condition 2

d f \leq \frac{\min (N P H S E G 1, N P H S E G 2)}{2 \times (13 \times \frac{N B T}{N T Q} - N P H S E G 2)}
