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.) See (Note 6)

Notes:
2. Response is clock dependent and will scale with Fs.
3. For Single-Speed Mode, the Measurement Bandwidth is 0.5465 Fs to 3 Fs.
For Double-Speed Mode, the Measurement Bandwidth is 0.577 Fs to 1.4 Fs.
For Quad-Speed Mode, the Measurement Bandwidth is 0.7 Fs to 1 Fs.
4. Refer to Figure 2.
5. De-emphasis is available only in Single-Speed Mode.
6. Amplitude vs. Frequency plots of this data are available in “Filter Plots” on page 18.
