Notes: 11. Slow Roll-Off interpolation filter is only available in control port mode.
12. Filter response is not tested but is guaranteed by design.
13. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 9 to 32) have
been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.
14. Single and Double Speed Mode Measurement Bandwidth is from stopband to 3 Fs.
Quad Speed Mode Measurement Bandwidth is from stopband to 1.34 Fs.
15. De-emphasis is available only in Single Speed Mode; Only 44.1kHz De-emphasis is available in Stand-
Alone Mode
