Soft Mute Operation
Soft mute operation is performed at digital domain. When SMUTE goes “1”, the output signal is attenuated by -
during
1024 LRCK cycles. When SMUTE is returned to “0”, the mute is cancelled and the output attenuation gradually changes
to 0dB during 1024 LRCK cycles. If the soft mute is cancelled within 1024 LRCK cycles after starting of the operation, the
attenuation is discontinued and returned to 0dB.
Soft mute function is independent to output volume, and those two functions are cascade connected.

Notes:
(1)
The output signal is attenuated by -
during 1024 LRCK cycles (1024/fs).
(2)
Analog output corresponding to digital input has the group delay (GD).
(3)
If the soft mute is cancelled within 1024 LRCK cycles, the attenuation is discontinued and returned to 0dB.
