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.)

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.
8. De-emphasis is available only in Single-Speed Mode; Only 44.1 kHz De-emphasis is available in Stand-
9. Amplitude vs. Frequency plots of this data are available in the “Appendix” on page 41.
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.
