COMBINED INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE
(Cont.)
Notes: 3. Slow Roll-Off interpolation filter is only available in control port mode.
4. For Single and 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 only available in Single Speed Mode; The 44.1kHz De-emphasis filter is the only filter
available in Stand-Alone Mode.
