Description
voltage

AFT output pin:
Offset of center voltage is adjusted by
using bus.
When AFT defeat SW is turned on (09
=
00), V
30
becomes a value determined by
external resistor-divider.
μ
of AFT is variable by impedance of
external resistor.
DC

External video input signal pin:
External video signal input pin and DC cut
input.
Typical 1 V[p-p].
AC
1 V[p-p]
(compost)
DC
approx. 2.0 V
32
Decoupling pin:
S-curve inside the IC is broad-band.
However, DC feedback should be applied
so that DC voltage of output signal becomes
constant.

SIF signal input pin:
Used in common as DC input pin for
sharpness control.
DC bias is applied from outside (for
sharpness control DC: 5 V to 7 V).
