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.

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

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).

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.

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.

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.
