Meaning of Zero-Crossing Detection Circuit In the conventional Serial Data Control Type Volume, Analog SW inside switches over simultaneously with Latch Condition Detector. And the operation completes. D29 DATA D30 D31 CLOCK Latch Conditions LATCH Noise Factor when Signal is present Audio Signal Signal GND(0V) In this case the changing noise occurs at the time of Latch Condition Detector, the Analog SW switches over (Zero-cross Detector Strobe occurs) in the moment that the Analog Signal cross Signal Ground (0V). DATA D29 D30 D31 CLOCK Latch Conditions LATCH Zero-cross Detector Strobe (Form signal from inside IC) Analog SW changing Signal GND (0V) Other,In the case of Audio Signal isn't inputted (No signal),even if only Zero-cross Detector Circuit detects Latch Condition, Analog SW doesn't switch over for the Audio Signal never cuts Signal Ground (0V). The Time Function switches the Analog SW after some time T. The related type of C(PIN23) and T is as the following. T=13.8E10 4 C (SEC) MITSUBISHI ELECTRIC 17 MITSUBISHI SOUND PROCESSOR ICs M61516FP 7.1ch ELECTRONIC VOLUME WITH 10 INPUT SELECTOR 2. Connection of Zero-Crossing Detector and Timer Setting Internal analog SW moves by [Zero-cross Detector Strobe] or [Compulsion SW of Timer Circuit]. For example, case of T=10msec. DATA D29 D30 D31 T=10msec Latch Conditions CLOCK LATCH Pattern 1 Zero-cross Detector Strobe (Form signal from inside IC) Audio Signal SW Changing Pattern 2 Zero-cross Detector Strobe (Form signal from inside IC) Audio Signal SW Changing In case of Pattern1, the Zero-cross Detector Strobe occurs with the Zero-cross Detector Function, and SW is switched. But in case of Pattern2, the Timer Function switches the Analog SW after T=10msec, for the Audio Input Signal didn't cut the Signal Ground after T=10msec which were set with the timer.
