1
L_out2
This pin is for output a sub-channel
left audio signal. The signals fed into
the chip via L_inV1, L_inV2, L_inS1,
L_inS2, or L_inTV is output from this
pin. The output resistance of this pin
is 45 Ω.
Furthermore, the signal output from ₁
this pin is pulse-converted for use in
self-diagnosis. The converted signal
is output from Sync Out.
This output can be muted in
combination with R_out2 by bus
control.
2
R_out2
This pin is for output a sub-channel
right audio signal. The signals fed
into the chip via R_inV1, R_inV2,
R_inS1, R_inS2, or R_inTV is output
from this pin. The output resistance
of this pin is 45 Ω.
Furthermore, the signal output from ₂
this pin is pulse-converted for use in
self-diagnosis. The converted signal
is output from Sync Out.
This output can be muted in
combination with L_out2 by bus
control.
3
Det in
This pin is for input a sync
separation signal. Input the signal
from Det Select to this pin with
capacitance coupling. The input
resistance of this pin is 18 kΩ.

The sync signal separated from Det
Select is outputted from Sync Out
for use in self-diagnosis.
