XV-CIE 1
l SYNC IN (pin No. 21)
Used to receive “L”-level (= OV) pulse for sync and “H”-level (= 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 R OUT, G OUT, B OUT (pin Nos. 32,34 and 36)
Used to output the primary-colour 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 IC.
l FRP (pin No. 39)
Used to receive the inverted signal.
l RGB INV (pin No. 40)
Used to receive voltage to switch the RGB output polarity according to the FRP polarity.
l SUB BRIGHT B (pin No. 41)
Used to receive DC voltage for fine adjustment of the B signal’s luminance level. This terminal is preset inside
the IC.
l SUB BRIGHT R (pin No. 42)
Used to receive DC voltage for fine adjustment of the R signal’s luminance level. This terminal is preset inside
the IC.
