10 / 46 page  10 DS568F1 CS4398 COMBINED INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE The filter characteristics have been normalized to the sample rate (Fs) and can be referenced to the desired sam- ple rate by multiplying the given characteristic by Fs.) (See note 9.) 4. Slow Roll-off interpolation filter is only available in Control Port mode. 5. Filter response is guaranteed by design. 6. Response is clock-dependent and will scale with Fs. 7. 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. For Quad-Speed Mode, the Measurement Bandwidth is from stopband to 1.34 Fs. 8. De-emphasis is available only in Single-Speed Mode; Only 44.1 kHz De-emphasis is available in Stand- Alone mode. 9. Amplitude vs. Frequency plots of this data are available in the “Appendix” on page 41.
