Passband Filtering
Each digital signal path in the IC includes options for
defining the path bandwidth (Figure 19). The playback
and record paths connected to DAI1 support both voice
and music filtering while the playback path connected to
DAI2 supports music filtering only.
The voice IIR filters provide greater than 70dB stopband
attenuation at frequencies above fS/2 to reduce aliasing.
Three selectable highpass filters eliminate unwanted low-
frequency signals.
Use music mode when processing high-fidelity audio
content. The music FIR filters reduce power consump-
tion and are linear phase to maintain stereo imaging.
An optional DC-blocking filter is available to eliminate
unwanted DC offset.
In music mode, a second set of FIR filters are available to
support sample rates greater than 50kHz. The filters can
be independently selected for DAI1 and DAI2 and sup-
port both the playback and record audio paths.
