Notes:
14. 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.
15. 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.
16. De-emphasis is only available in Single-Speed Mode.
