6. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 5-12) have
been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.
7. For Base-Rate Mode, the measurement bandwidth is 0.5465 Fs to 3 Fs.
For High-Rate Mode, the measurement bandwidth is 0.577 Fs to 1.4 Fs.
8. De-emphasis is not available in High-Rate Mode.
