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.)

2. Response is clock-dependent and will scale with Fs.

3. 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.

4. De-emphasis is available only in Single-Speed Mode.

5. Amplitude vs. Frequency plots of this data are available in “Digital Filter Response Plots” on page 15.
