Notes: 2. Filter response is not tested but is guaranteed by design.
3. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 15-22) have
been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.
4. 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.
5. De-emphasis is not available in High-Rate Mode.
6. Refer to Figure 2.
