Notes: 2. Filter response is guaranteed by design.

3. Filter characteristics scale with output sample rate. For output sample rates, Fs, other than 48 kHz, the

0.01 dB passband edge is 0.4535x Fs and the stopband edge is 0.625x Fs.

4. The analog modulator samples the input at 6.144 MHz for an Fs equal to 48 kHz. There is no rejection

of input signals which are multiples of the sampling frequency (n x 6.144 MHz ±21.8 kHz where

n = 0,1,2,3...).
