Notes:
9. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 39 to 62) have
been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.
10. 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.
11. De-emphasis is available only in Single-Speed Mode.
