12. Plots of this data are contained in the “Appendix” on page 47. See Figure 21 through Figure 44.
9. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 21 to 44) have
been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.
Quad Speed Mode Measurement Bandwidth is from stopband to 1.34 Fs.
