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 12))
Notes:
8. Slow Roll-off interpolation filter is only available in Software Mode.
9. Response is clock dependent and will scale with Fs.
10. 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.
11. De-emphasis is available only in Single-Speed Mode; Only 44.1 kHz De-emphasis is available in Hardware
Mode.
12. Amplitude vs. Frequency plots of this data are available in the “Filter Response Plots” on page 43.
