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 36.

Response is clock dependent.
The Measurement Bandwidth is from stopband to 3 Fs.
De-emphasis is available only in Single-Speed Mode; Only 44.1 kHz De-emphasis is available in Stand-
Alone Mode.
Slow Roll-off interpolation filter is only available in Control Port Mode.
