COMBINED INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE

(Continued)

Notes:

2.

Slow Roll-off interpolation filter is only available in Control Port mode.

3.

Response is clock dependent and will scale with Fs.

4.

For Single-Speed Mode, the Measurement Bandwidth is from stopband to 3 Fs.

For Double-Speed Mode, the Measurement Bandwidth is from stopband to 3 Fs.

For Quad-Speed Mode, the Measurement Bandwidth is from stopband to 1.34 Fs.

5.

De-emphasis is available only in Single-Speed Mode; Only 44.1 kHz De-emphasis is available in Stand-

Alone Mode.

6.

Amplitude vs. Frequency plots of this data are available in the “Digital Filter Response Plots” on

page 31.
