8 / 26 page 8 DS803F1 CS4353 9. SDIN = 0. AOUT_REF input test signal is a 60 Hz, 50 mVpp sine wave. Measured by applying the test signal into the AOUT_REF pin and measuring the resulting output amplitude on the AOUTx pin. Spec- ification calculated by: 10. Applying a DC voltage on the AOUT_REF pin will cause a DC offset on the DAC output. See Section 4.1.3 for more information. 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. Notes: 11. Response is clock-dependent and will scale with Fs. 12. For Single- and 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. 13. De-emphasis is available only in Single-Speed Mode. 14. Amplitude vs. Frequency plots of this data are available in “Digital Filter Response Plots” on page 21.
