10 / 73 page 10 DS603F1 CS42418 D/A DIGITAL FILTER CHARACTERISTICS Notes: 9. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 39 to 62) have been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs. 10. 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. 11. De-emphasis is available only in Single-Speed Mode.
