7. Filter response is guaranteed by design.
8. 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.
For Quad-Speed Mode, the Measurement Bandwidth is 0.7 Fs to 1 Fs.
9. De-emphasis is available only in Single-Speed Mode.
10. Response is clock dependent and will scale with Fs. Note that the amplitude vs. frequency plots of this
