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 the data in the table below
are available in “Digital Filter Response Plots” on page 16.)

Response is clock-dependent and will scale with Fs.
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.
De-emphasis is available only in Single-Speed Mode.
