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
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
It should be noted that EF is only a defined output in CD ROM modes.
