In Software Mode, the required de-emphasis filter coefficients for 32 kHz, 44.1 kHz, or 48 kHz are selected
via the de-emphasis control bits.
In Hardware Mode, only the 44.1 kHz coefficient is available (enabled through the M2 pin). If the input sam-
ple rate is not 44.1 kHz and de-emphasis has been selected, the corner frequencies of the de-emphasis
filter will be scaled by a factor of the actual Fs over 44,100.
ATAPI Specification
The CS4382A implements the channel mixing functions of the ATAPI CD-ROM specification. The
ATAPI functions are applied per A-B pair. Refer to
tion.
