Soft Mute
Soft mute operation is performed in the digital domain. When the SMUTE bit goes to “1”, the output signal is attenuated
by
∞
(“0”) during the cycle set by the DVTM bit. When the SMUTE bit is returned to “0”, the mute is cancelled and the
output attenuation gradually changes to the value set by the DVL/R7-0 bits during the cycle set of the DVTM bit. If the
soft mute is cancelled within the cycle set by the DVTM bit after starting the operation, the attenuation is discontinued and
returned to the value set by the DVL/R7-0 bits. The soft mute is effective for changing the signal source without stopping
the signal transmission (Figure 39).

(1)
The output signal is attenuated until
∞
(“0”) by the cycle set by the DVTM bit.
(2)
Analog output corresponding to digital input has the group delay (GD).
(3)
If the soft mute is cancelled within the cycle set by the DVTM bit, the attenuation is discounted and returned to the
value set by the DVL/R7-0 bits.
