R_inS1
This pin is for input a right audio
signal from an external source (S1
channel). The signal fed into this pin
is presented to R_out1 and R_out2.
13
The input dynamic range of this pin
is 6.5 Vp-p and the input resistance is
70 kΩ.

C_inS1
This pin is for input a chroma signal
from an external source (S1
channel). It also functions as an
S-mode select switch for the S1
channel. The S mode is selected
when the pin voltage is 2.25 V or
less. The signal fed into this pin is
presented to C_out directly and to
14
V_out1 and V_out2 after being
combined with the Y_inS1 signal.
The input dynamic range of this pin
is 2.0 Vp-p and the input resistance is
30 kΩ.

L_inS2
This pin is for input a left audio
signal from an external source (S2
channel). The signal fed into this pin
is presented to L_out1 and L_out2.

Y/V_inS2
This pin is for input a luminance
signal or composite aoudio signal
from an external source (S2
channel). The signal fed into this pin
is presented to V_out1, V_out2, Y_out,
and C_out.
