CXA2546Q  
(4) Zero-cross detector and timer  
A built-in zero-cross detection circuit is used to detect the zero-cross points of the input signal. When data  
arrived at the IC, they are executed at the next zero-cross point or when there is no input signal. This is to  
minimize 'click' noise during the transition of levels.  
The timer circuit is added to ensure that the data is executed even when a zero-cross point is not detected  
after a certain period of time from the falling edge of the CE pulse.  
Time constant=(0.5/10µ) × C [s]

(6) Power-off mute  
When VCC goes below 5 V, the output stage bias of the fader output pins FNTO1, FNTO2, REO1, and  
REO2 is turned off and the pins go to high impedance. This operation prevents popping noises caused by  
the output pin potential deviating from VCC/2 when the power is turned off.
