Serial Port Format Selection
The desired serial audio format is selected with the DIF2, DIF1 and DIF0 pins. For an explanation of the
required relationship between the LRCK, SCLK and SDIN, see
on the rising edge of SCLK. TDM Mode requires the selection of which stereo pair time “slot” is used to out-
put data as shown in
De-Emphasis Control
When pulled to VLC, the DEM pin activates the 44.1 kHz de-emphasis filter. When pulled to GND, the DEM
pin turns off the de-emphasis filter.
Popguard Transient Control
In Stand-Alone Mode, Popguard is enabled by default. Popguard can be defeated in Stand-Alone Mode by
placing a 47 kΩ resistor between RMCK and VLS.
