SERVICE MANUAL
This outputted can be muted independently of TV-L out by bus
control.
17 TV-L out
This pin is for output left audio signal. The signal fed into TV-L
in, V1-L in, or V2-L in is outputted from this pin.
This output can be muted independently of TV-R out by bus
control.
18 Y out
This pin is for output a luminance signal. The signal fed into
V1-V/Y in, V2-V in, or TV-V in is outputted from this pin.
19 I/O
－１
This is an ADC input/DAC output pin. The ADC is a 2-level
detection type
(1 bits). The threshold level is 3.0 V. The DAC (1 bit) is an
open-drain output. Make sure that the current flowing into this
pin is 2.0 mA or less.
20 C out
This pin is for output a chroma signal. The signal fed into V1-C
in, V1-V in, V2-V in , or TV-V in is outputted from this pin.
21 I/O
－２
This is an ADC input/DAC output pin. The ADC is a 2-level
detection type (1 bits). The threshold level is 3.0 V.
The DAC (1 bit) is an open-drain output. Make sure that the
current flowing into this pin is 2.0 mA or less.
22 V out
This pin is for output the main channel composite video signal.
The signal fed into TV-V in, V1-V in, V2-V in, or V1-Y in +_V1-C
in is outputted from this pin.
This output can be muted by bus control.
23 Mon-R out
This pin is for monitor-output right audio signal. The signals fed
into the chip via V1-R in, V2-R in, or TV-R in is output from this
pin.
This output can be muted in combination with Mon-L out by bus
control.
24 Mon-L out
This pin is for monitor-output left audio signal. The signals fed
into the chip via V1-L in, V2-L in, or TV-L in is output from this
pin.
This output can be muted in combination with Mon-R out by
bus control.
