Input Crossbar Mixers
The TAS3103 has four serial input ports—SDIN1, SDIN2, SDIN3 and SDIN4. SDIN1, SDIN2, and SDIN3 provide the
input resources to process 5.1 channel audio in two TAS3103 chips. SDIN4 provides the capability to multiplex
between a full 5.1 channel system and a stereo source or an information/warning audio message as might be found
in an automotive application.
Each serial input port is assigned two internal processing nodes. The mixers following these internal processing
nodes serve to distribute the input audio data to various processing nodes within the TAS3103. Figure 37 shows
the assignment of the internal processing nodes to the serial input ports. Two cases are shown in Figure 37—
discrete mode and TDM mode.
The input crossbar mixer topology for internal processing nodes A, B, C, D, E and F is shown in Figure 38. Each
of the six nodes is assigned six mixers. These six mixers provide the ability to route the incoming serial port data on
SDIN1, SDIN2, and SDIN3 to:
Processing node d—bypassing effects block and directly feeding monaural CH1
Processing node e—bypassing effects block and directly feeding monaural CH2
Processing node f—directly feeding the section of the effects block assigned to monaural CH3
Processing nodes a and b—directly feeding paths that contain the reverb delay elements assigned to CH1
and CH2
Processing node c—directly feeding an effects block path assigned to CH1 and CH2 that bypasses all
reverb delay elements.
The ability to route all input nodes to the same set of processing nodes fully decouples the input order (what audio
components are wired to which serial input ports) from the processing flow. As is seen in the discussion of the output
crossbar mixers, the output serial ports are fully decoupled from the three monaural channels (any monaural channel
output can be routed to either the left or the right side of any output port). The TAS3103 thus provides full flexibility
in the routing of audio data into and out of the chip.
The mixer topology for internal processing nodes g and h is shown in Figure 39. Nodes g and h are each assigned
three mixers. The mixers provide the ability to route the incoming data on serial port SDIN4 to:
Output processing nodes to facilitate input to output pass through
CH1/CH2 effects block input nodes that bypass reverb delay
CH3 effects block input node
