7 / 28 page CS4340 DS297PP3 7 ANALOG CHARACTERISTICS (Continued) Notes: 4. Refer to Figure 14. 5. Filter response is guaranteed by design. 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.
