COMBINED INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE
(Continued)
Notes:
2. Slow Roll-off interpolation filter is only available in Control Port mode.
3. Response is clock dependent and will scale with Fs.
4. 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.
5. De-emphasis is available only in Single-Speed Mode; Only 44.1 kHz De-emphasis is available in Stand-
Alone Mode.
6. Amplitude vs. Frequency plots of this data are available in the “Digital Filter Response Plots” on
page 31.
