Input Crossbar Mixer

The TAS5508C 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 Figure 2-11. The control parameters

for the input crossbar mixer are programmable via the I2C interface. See the Input Mixer Registers

(0x41–0x48, Channels 1–8), Section 7.16, for more information.

Biquad Filters

For 32-kHz to 96-kHz data, the TAS5508C provides 56 biquads across the eight channels (seven per

channel).

For 176.4-kHz and 192-kHz data, the TAS5508C has 21 biquads across the three channels (seven per

channel). All of the biquad filters are second-order direct form I structure.
