NOTES
1Lower sampling rates than those given by this formula are possible, but the jitter rejection will decrease.
2Refer to the Typical Performance Characteristics section for DNR and THD + N numbers over a wide range of input and output sample rates.
3For any other ratio, minimum THD + N will be better than –115 dB. Please refer to detailed performance plots.
Specifications subject to change without notice.
