Notes: 10. Response is clock-dependent and will scale with Fs. Note that the amplitude vs. frequency plots of this
data (Figures 31 to 42) have been normalized to Fs and can be de-normalized by multiplying the X-axis
scale by Fs.
11. 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.
12. De-emphasis is available only in Single-Speed Mode.
