... APPLICATIONS The CS4344 family accepts data at standard audio sample rates including 48, 44.1 and 32 kHz in SSM, 96, 88.2 and 64 kHz in DSM, and 192, 176.4 and 128 kHz in QSM. Audio data is input via the serial data input pin (SDIN). The Left/Right Clock (LRCK) determines which channel is currently being input on SDIN, and the optional Serial Clock (SCLK) clocks audio data into the input data buffer ...

... De-Emphasis The CS4344 family includes on-chip digital de-emphasis. equal to 44.1 kHz. The frequency response of the de-emphasis curve will scale proportionally with changes in sample rate, Fs. The de-emphasis filter is active (inactive) if the DEM/SCLK pin is low (high) for 5 consecutive falling edges of LRCK. This function is available only in the internal serial clock mode ...
