Input Crossbar Mixer
The TAS5508A has a full 8 8 input crossbar mixer. This mixer permits each signal-processing channel
input to be any ratio of any of the eight input channels, as shown in
for the input crossbar mixer are programmable via the I
(0x41–0x48, Channels 1–8),

Biquad Filters
For 32-kHz to 96-kHz data, the TAS5508A provides 56 biquads across the eight channels (seven per
channel).
For 176.4-kHz and 192-kHz data, the TAS5508A has 21 biquads across the three channels (seven per
channel). All of the biquad filters are second-order direct form I structure.
