C
; AVDD,DVDD=4.5V
5.5V; fs=44.1kHz)
Parameter
Digital Filter
Passband -0.2dB (Note 9 )
-6.0dB
Stopband (Note 9 )
Passband Ripple
Stopband Attenuation
Group Delay (Note 10 )
Digital Filter + SCF + CTF
Frequency Response 0
20.0kHz
Note: 9 . The passband and stopband frequencies scale with fs.
For example, PB=0.4535*fs(@-0.2dB), SB=0.55*fs.
10 . The calculating delay time which occurred by digital filtering. This time is from setting the 16bit
data of both channels to input register to the output of analog signal.
