Notes: 7. See Section 4.2.7 for details.
8. Filter response is not tested but is guaranteed by design.
9. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 14 through 21)
have been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.
10. Referenced to a 1 kHz, full-scale sine wave.
11. For Single Speed Mode, the measurement bandwidth is 0.5465 Fs to 3 Fs.
For Double Speed Mode, the measurement bandwidth is 0.577 Fs to 1.4 Fs.
12. De-emphasis is not available in Double Speed Mode.
