l
SYNC IN (pin No. 21)
Used to receive OV) pulse for sync and 3V) pulse otherwise. The sync signal received
and the sync signal separated by the sync separation circuit are fed through an OR gate and then into the
gate pulse generator circuit.
l
TIME CONSTANT (pin No. 22)
Used to make gate pulse width setting according to CR time constant.
l
PICTURE (pin No. 23)
Used to receive DC voltage for adjusting the video system’s frequency characteristic.
l
KILLER FILTER (pin No. 24)
Used to connect a filter for killer detection.
l
TINT (pin No. 25)
Used to receive DC voltage to adjust the tint.
l
VCO OUT (pin No. 26)
Used to output the oscillator circuit signal.
l
APC FILTER (pin No. 27)
Used to connect an APC detection filter.
l
VCO IN (pin No. 28)
Used to receive the oscillator circuit signal.
. GND (pin No. 29)
Grounding terminal.
l
OUT, OUT, OUT (pin Nos. and 36)
Used to output the signals that are inverted according to the inversion signal.
l
VCC2 (pin No. 33)
Used to connect the positive-polarity power for RGB output.
. OUT DC DET (pin No. 35)
Used to connect a capacitor to detect the output DC bias.
l
RGB AMPLITUDE (pin No. 38)
Used to adjust the amplitude between the inverted RGB output and the non-inverted one. This terminal is
preset inside the
l
FRP (pin No. 39)
Used to receive the inverted signal.
l
RGB (pin No. 40)
Used to receive voltage to switch the RGB output polarity according to the FRP polarity.
l
SUB BRIGHT (pin No. 41)
Used to receive DC voltage for fine adjustment of the signal’s luminance level. This terminal is preset inside
the
l
SUB BRIGHT (pin No. 42)
Used to receive DC voltage for fine adjustment of the signal’s luminance level. This terminal is preset inside
