7 / 23 page CS4344/5/6/8 DS613PP2 7 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 sample 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 “Appendix” on page 21.
