Soft
mute
operation
Soft mute operation is performed at digital domain. When SMUTE goes to “H”, the output signal is attenuated by -
during 1024 LRCK cycles. When SMUTE is returned to “L”, 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 the
operation, the attenuation is discontinued and returned to 0dB. The soft mute is effective for changing the signal source
without stopping the signal transmission.

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.
