The Mode Select pins determine the operational mode of the device as detailed in Tables 9-14. The op-
tions include:
Selection of the Digital Interface Format which determines the required relationship between the
Left/Right clock, serial clock and serial data as detailed in Figures 29-33
Selection of the standard 15 s/50 s digital de-emphasis filter response, Figure 28, which requires re-
configuration of the digital filter to maintain the proper filter response for 32, 44.1 or 48 kHz sample rates.
Selection of the appropriate clocking mode to match the input sample rates.
Access to the Direct Stream Digital Mode
Access to the 8x Interpolation Input Mode
