Notes: 13. 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.
14. 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.
15. De-emphasis is only available in Single Speed Mode.
