R_outTV
This pin is for output only the signal
that is forwarded from R_inTV. The
output resistance of this pin is 45 Ω.
39
This output can be muted in
combination with L_outTV by bus
control.

O5
This is a 1 bit DAC output pin. This
is an open-collector output. Make
sure that the current flowing into this
41
pin is 2.0 mA or less.
42
V_out2
This pin is for output a sub-channel
composite video signal. The signal
fed into V_inTV, V_inV1, V_inV2, V_inS1,
V_inS2, Y_inS1 + C_inS1, or Y_inS2 +
C_inS2 is outputted from this pin. The
output resistance of this pin is 25 Ω.
42
The same signal is also outputted
from Det Select as a sync
separation signal.
