Notes: 2. Referenced to typical fullscale differential input voltage.
3. The filter characteristics have been normalized to the sample rate (Fs) and can be referenced to the
desired sample rate by multiplying the given characteristic by 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; n = 0, 1, ...).
