Notes:

4. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 7-18) have

been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.

5. For Operational Mode 0, the Measurement Bandwidth is 0.5465 Fs to 1.4 Fs.

For Operational Mode 1, the Measurement Bandwidth is 0.570 Fs to 1.4 Fs.

For Operational Mode 2, 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 Operational Mode 0.
