COMBINED DIGITAL AND ON-CHIP ANALOG FILTER CHARACTERISTICS
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. Reference level (0 dB) is set at 997 Hz. (Note 11)
Notes: 8.
Response is clock-dependent and will scale with Fs.
9.
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.
10. De-emphasis is available only in Single-Speed Mode.
11. Amplitude vs. frequency plots of this data are available in “Combined Digital and On-chip Analog Filter
