Y_in
This pin is for input a luminance
signal from an external comb filter.
The signal fed into this pin is
presented to Y_out.
30
The input dynamic range of this pin
is 5.5 Vp-p and the input resistance is
60 kΩ.

R_inV2
This pin is for input a right audio
signal from an external source (V2
channel). This pin can also be used
for PIP signal input. The signal fed
into this pin is presented to R_out1
and R_out2.
31
The input dynamic range of this pin
is 6.5 Vp-p and the input resistance is
70 kΩ.

V_CC
This pin is for input a chroma signal
from an external comb filter. The
signal fed into this pin is presented
to C_out.
The input dynamic range of this pin
is 5.5 Vp-p and the input resistance is 32
60 kΩ.
This pin also functions as a audio
mute switch. The entire audio output
can be muted by pulling the voltage
on this pin below 2.25 V.
This is the power supply pin. Apply 9
V to this pin. The current
consumption of this pin is 47 mA.

C_out
This pin is for output a chroma
signal. The signal fed into C_in,
C_inS1, C_inS2, V_inV1, V_inV2,
Y/V_inS1, Y/V_inS2, or V_inTV is
outputted from this pin. The output
resistance of this pin is 25 Ω.

The same signal is also outputted
from Det Select as a sync
separation signal.
