CS4362A
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 12.)

Notes:
8. Slow Roll-off interpolation filter is only available in software mode.
9. Response is clock dependent and will scale with Fs.
10. For Single-Speed Mode, the Measurement Bandwidth is from stopband to 3 Fs.
For 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.
11. De-emphasis is available only in Single-Speed Mode; Only 44.1 kHz De-emphasis is available in hard-
ware mode.
12. Amplitude vs. Frequency plots of this data are available starting on page 43.
