5. STAND-ALONE OPERATION

5.1

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 Figures 11-13. For all formats, SDIN is valid

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 Table 2 and Figure 15.

5.2

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.

5.3

Popguard Transient Control

In Stand-Alone Mode, Popguard is enabled by default. Popguard can be defeated in Stand-Alone Mode by

placing a 47 k

Ω resistor between RMCK and VLS.
