SHARP ROLL-OFF FILTER CHARACTERISTICS
(Ta = 25

Parameter
Digital filter
Passband

-6.0dB
Stopband (Note 10)
Passband Ripple
Stopband Attenuation
Group Delay (Note 11)
Digital Filter + SCF
Frequency Response
80.0kHz
Fs=192kHz
Note 10. The passband and stopband frequencies scale with fs(system sampling rate). For example, PB=0.4535×fs
(@
±
0.05dB), SB=0.546×fs.
Note 11. Calculated delay time caused by the digital filter. This time is measured from when the serial data of both
channels is in the input register to the output of the analog signal.
