Mute Control
(
Output
) - The Mute Control pins go high during power-up initialization, reset, muting,
power-down or if the master clock to left/right clock frequency ratio is incorrect. These pins are intended
to be used as a control for external mute circuits to prevent the clicks and pops that can occur in any sin-
gle supply system. The use of external mute circuits are not mandatory but may be desired for designs
requiring the absolute minimum in extraneous clicks and pops.
