6 / 36 page CS4397 6 DS333PP1 ANALOG CHARACTERISTICS (Continued) Notes: 4. Response is clock dependent and will scale with Fs. Note that the response plots ( Figures 9-28) have been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs. 5. For Single-Speed Mode, the Measurement Bandwidth is 0.5465 Fs to 1.4 Fs. For Double-Speed Mode, the Measurement Bandwidth is 0.570 Fs to 1.4 Fs. For Quad-Speed Mode, the Measurement Bandwidth is 0.635 Fs to 1.3 Fs. 6. Group Delay for Fs=48 kHz 37/48 kHz=770 µs 7. De-emphasis is available only in Single Speed Mode.
