Audio data from the SAA7324 can be sent to an external
DAC, identical to the SAA737x series. This is similar to the
‘loopback’ mode, but in this case the internal DAC outputs
can be held at zero. i.e. shadow register 7 is set to XX00.
The SAA7324 is compatible with a wide range of external
DACs. Eleven formats are supported and are given in
Table 5. Figures 12 and 13 show the Philips I
the EIAJ data formats respectively. When the decoder is
operated in lock-to-disc mode, the SCLK frequency is
dependent on the disc speed factor ‘d’.

Note
1. In this mode the first 16 bits contain data, but if any of the fade, attenuate or de-emphasis filter functions are activated

When using an external DAC (or when using the onboard
DAC in non-loopback mode), the serial data inputs to the
onboard DAC (SCLI, SDI and WCLI) should be left
unconnected.
