De-Emphasis
The CS4361 includes on-chip digital de-emphasis. Figure 11 shows the de-emphasis curve for Fs equal to
44.1 kHz. The frequency response of the de-emphasis curve will scale proportionally with changes in sam-
ple rate, Fs. The de-emphasis filter is active (inactive) if the DEM/SCLK pin is low (high) for five consecutive
falling edges of LRCK. This function is available only in the internal Serial Clock Mode when LRCK < 50 kHz.

Mode Select
Mode selection is determined by the Mode Select pin. The value of this pin is locked 1024 LRCK cycles after
RST is released. This pin requires a specific connection to supply, ground, MCLK, or LRCK as outlined in
Table 2. Mode Pin Settings
