Product specification
Digital servo processor and
Compact Disc decoder (CD7)
SAA7371
7.8
DAC interface
The SAA7371 is compatible with a wide range of digital-to-analog converters (DACs). Eleven formats are supported and
are given in Table 4. Figures 11 and 12 show the Philips I
2
S-bus and 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’. All formats are
MSB first and f
s
is (44.1
×
n) kHz. The polarity of the WCLK and the data can be inverted; selectable by register 7.
It should be noted that EF is only a defined output in CD ROM modes.

DAC interface formats
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
then the first 18 bits contain data.
