COMBINED INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE

The filter characteristics have been normalized to the sample rate (Fs) and can be referenced to the desired sam-

ple rate by multiplying the given characteristic by Fs. Amplitude vs. Frequency plots of this data are available in the

“Filter Plots” on page 35

Notes:

3.

Response is clock dependent.

4.

The Measurement Bandwidth is from stopband to 3 Fs.

5.

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

Mode.

6.

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