Notes: 2. Slow Roll-off interpolation filter is only available in Control Port mode.
3. Response is clock dependent and will scale with Fs.
4. For Single Speed Mode, the Measurement Bandwidth is from stopband to 3 Fs.
For Double Speed Mode, the Measurement Bandwidth is from stopband to 3 Fs.
For Quad Speed Mode, the Measurement Bandwidth is from stopband to 1.34 Fs.
5. De-emphasis is available only in Single Speed Mode; Only 44.1 kHz De-emphasis is available in Stand-
Alone Mode.
6. Amplitude vs. Frequency plots of this data are available in “Appendix” on page 37.
