Datapath
The ADAV803 features a digital input/output switching/
multiplexing matrix that gives flexibility to the range of possible
input and output connections. Digital input ports include
playback and auxiliary input (both 3-wire digital), and S/PDIF
(single-wire to the on-chip receiver). Output ports include the
record and auxiliary output ports (both 3-wire digital) and the
S/PDIF port (single-wire from the on-chip transmitter).
Internally, the DIR and DIT are interfaced via 3-wire interfaces.
The datapath for each input and output port is selected by
programming Datapath Control Register 1 and Datapath
Control Register 2. Figure 52 shows the internal datapath
structure of the ADAV803.
