The PCM-I
processing to the DSD_PCM output lines, or further processed inside the
SAA7893HL. When directly coupled, only a combinatorial delay must be taken into
account; no dependency on any clock signal (see
characteristics, when audio processing must be performed, are given in
Section
When no processing is done inside the SAA7893HL with respect to the I
input stream, this input stream is sent via a multiplexer to the I
no clocking is done on this signal, meaning that also no locked audio clock needs to
be present.
