NOTES
1
Lower sampling rates than given by this formula are possible, but the jitter rejection will decrease.
2
Refer to the Typical Performance Characteristics section for DNR and THD + N numbers over wide range of input and output sample rates.
3
For any other sample rate ratio, the minimum THD + N will be better than –117 dB. Please refer to detailed performance plots.
