Note:

1. Filter response is not tested but is guaranteed by design.

2. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 8-15) have

been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.

3. Referenced to a 1 kHz, full-scale sine wave.

4. For Single Speed Mode, the measurement bandwidth is 0.5465 Fs to 3 Fs.

For Double Speed Mode, the measurement bandwidth is 0.577 Fs to 1.4 Fs.

5. De-emphasis is not available in double speed mode.
