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
