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 5)

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. De-emphasis is available only in Single Speed Mode.
5. Amplitude vs. Frequency plots of this data are available in “Appendix” on page 21.
