2.5 Combined Interpolation and On-Chip Analog Filter Response
The filter characteristics have been normalized to the sample rate (Fs) and is referenced to the desired sam-
ple rate by multiplying the given characteristic by Fs. Amplitude vs. Frequency plots of this data are available
in the “Filter Plots” on page 35.
Notes: 6. Response is clock dependent.
7. 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-
Alone Mode.
9. Slow Roll-off interpolation filter is only available in Control Port Mode.
