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
s
7. De-emphasis is available only in Single Speed Mode.
