StopBand Attenuation
Group Delay
Passband Group Delay Deviation 0 - 40 kHz
De-emphasis Error
(Relative to 1 kHz)
3. Filter response is not tested but is guaranteed by design.
5. Referenced to a 1 kHz, full-scale sine wave.
6. For Base-Rate Mode, the measurement bandwidth is 0.5465 Fs to 3 Fs.
7. De-emphasis is not available in High-Rate Mode.
4. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 9-16) have
been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.
For High-Rate Mode, the measurement bandwidth is 0.577 Fs to 1.4 Fs.
