Figure 15. Digital Audio Signal Routing
the playback path in the digital audio interface to allow
the IC’s full complement of digital signal processing to
be used. Loopback allows digital data input to either
SDINS1 or SDINS2 to be routed from one interface to the
other for output on SDOUTS2 or SDOUTS1. Both inter-
faces must be configured for the same sample rate, but
the interface format need not be the same. This allows
the IC to route audio data from one device to another,
converting the data format as needed. Figure 15 shows
the available digital signal routing options.
