CS4270
DAC 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
)
5.
Amplitude vs. Frequency plots of this data are available in
Section 11. “Appendix” on page 42
. See
Figures 19
through
42
.
6.
Response is clock dependent and will scale with Fs.
7.
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.
8.
De-emphasis is available only in Single-Speed Mode.
