Referenced to typical full-scale differential input voltage (2 Vrms) 2. Filter characteristics scale with output sample rate. For output sample rates, Fs, other than 48 kHz, the 0.01 dB passband edge is 0.4535xFs and the stopband edge is 0.625xFs. 3. 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...). 4. Group delay for Fs = 48 kHz, tgd = 15/48 kHz = 312 µs * Parameter definitions are given at the end of this data sheet. Specifications are subject to change without notice. CS4222 2 DS236PP3 |
