Balance/Loudness
M61516FP has balance output (L/R channel) for external A/D converter. The balance output (negative side/pin55,57)can use not only balance output also loudness capacitor connection terminal.(for loudness frequency setting) Please choose balance output or loudness capacitor connection terminal comply with your system. Balance output and loudness function can't be used at the same time. 1.Balance output Balance/Loudness function switch setting:Balance Output(D26=0,D30=0,D31=0)

ZERO-CROSSING DETECTION CIRCUIT
1. 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. DATA CLOCK LATCH Audio Signal Signal GND(0V) Noise Factor when Signal is present D29 D30 D31 Latch Conditions
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 CLOCK LATCH
D29
D30
D31 Latch Conditions 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

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. Timer Setting Time setting for Frequency band of Input Audio Signal.
