The capacitance which smoothes and protects the difference of the output DC bias
from (VCC + VEE) /2.
The inverted primary color signal is output according to the inversion signal.
Not used.
The amplitude between the normal and inverted RGB output can be adjusted. This
pin is preset in the IC.
The inversion signal is input.
GND
The brightness of the B signal can be finely adjusted by the DC voltage which is
input to this pin. This pin is preset in the IC.
The brightness of the R signal can be finely adjusted by the DC voltage which is
input to this pin. This pin is preset in the IC.
The Y-signal can be adjusted by the DC voltage which is input to this pin.
The change point of the DC voltage gain of
correction can be set by the DC voltage which is
input to this pin.(Refer to the' right figure.) The
-correction pin is preset in the IC.
The change point of the DC voltage gain of
correction can be set by the DC voltage which is
input to this pin.(Refer to the right figure.)
The peak limiter level on the white peak of the primary color output can be set by
the DC voltage which is input to this pin.
The contrast of the B signal can be finely adjusted by the DC voltage which is input
to this pin. This pin is preset in the IC.
The contrast of the R signal can be finely adjusted by the DC voltage which is input
to this pin. This pin is preset in the IC.
