The SAA7893HL has 12 output lines: 8 lines are allocated for connection to a
6-channel DAC and 4 are for connection to a 2-channel DAC or a 75 Hz reference
signal. The DSD data on the MCH output lines are outputted 6412 clocks after the
positive edge of the 75 Hz signal, if no additional post-processing is done.
The SA-MP delivers extra flexibility when connecting to different DAC types, which
can be: DSD only, PCM only or multi standard (DSD + PCM)]. In
Table 31
the signal
allocation is given for the 6-channel output in DSD and in PCM-I
2
S mode.
In
Table 32
the signal allocation is given for the DSD/PCM signals to be connected to
the stereo DAC.
