Figure 2-10. TAS5508B Digital Audio Processing
The TAS5508B has a full 8
×8 input crossbar mixer. This mixer permits each signal-processing channel
input to be any mix of any of the eight input channels, as shown in Figure 2-11. The control parameters for
the input crossbar mixer are programmable via the I2C interface. See the Input Mixer Registers, Channels
1–8 (0x41–0x48), Section 7.13, for more information.
Figure 2-11. Input Crossbar Mixer
For 32-kHz to 96-kHz data, the TAS5508B provides 56 biquads across the eight channels (seven per
channel).
For 176.4-kHz and 192-kHz data, the TAS5508B has 21 biquads across the three channels (seven per
channel). All of the biquad filters are second-order direct form I structure.
