21 / 66 page ![]() DS647PP2 21 COMBINED DAC INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE Notes: 13. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 34 to 45) have been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs. 14. Single and Double Speed Mode Measurement Bandwidth is from Stopband to 3 Fs. Quad Speed Mode Measurement Bandwidth is from Stopband to 1.34 Fs. 15. De-emphasis is only available in Single Speed Mode.
