Mute Control
The Mute Control pins go active during power-up initialization, reset, muting, or if the MCLK to LRCK ratio
is incorrect. These pins are intended to be used as control for external mute circuits to prevent the clicks
and pops that can occur in any single-ended single supply system.
Use of the Mute Control function is not mandatory but recommended for designs requiring the absolute min-
imum in extraneous clicks and pops. Also, use of the Mute Control function can enable the system designer
to achieve idle channel noise/signal-to-noise ratios which are only limited by the external mute circuit.
Please see the CDB4382A data sheet for a suggested mute circuit.
