De-Emphasis Control
The device includes on-chip digital de-emphasis.
kHz. The frequency response of the de-emphasis curve will scale proportionally with changes in sample
rate, Fs.
Note:
least 32 cycles per LRCK period in format 2, 48 cycles in format 3, 40 cycles in format 4, and 36 cycles
in format 5.
