n
Zero detection
When the input data at both channels is continuously zeros for 8192 LRCK cycles, DZF pin goes to “H”. DZF pin channel
immediately goes to “L” if the input data is not zero after going DZF “H”. If RSTN bit is “0”, DZF pin goes to “H”. DZF
pin goes to “L” at 4~5/fs after RSTN bit returns to “1”.
n
Soft mute operation
Soft mute operation is performed at digital domain. When the SMUTE pin goes to “H”, the output signal is attenuated by
-
∞
during 1024 LRCK cycles. When the SMUTE pin 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) The analog output corresponding to the digital input has a group delay, GD.
(3) If the soft mute is cancelled within 1024 LRCK cycles, the attenuation is discontinued and returned to 0dB.
(4) When the input data at both channels is continuously zeros for 8192 LRCK cycles, DZF pin goes to “H”. DZF pin
immediately goes to “L” if the input data is not zero after going DZF “H”.
