Audio data from the CD7 II decoder can be sent direct 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 SAA7327 is compatible with a wide range
of external DACs. Eleven formats are supported and are
given in Table 4. Figures 12 and 13 show the Philips
I
decoder is operated in lock-to-disc mode, the SCLK
frequency is dependent on the disc speed factor ‘d’.

The polarity of the WCLK and the data can be inverted;
selectable by decoder register 7. It should be noted that
EF is only a defined output in CD-ROM and 1f
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.
