Description
ABL control signal input and VSAW high
voltage fluctuation compensation signal
input.
High voltage compensation has linear
control characteristics for the pin voltage
range of about 8V to 1V. The control
characteristics can be varied through
EHT-V control of the bus. ABL begins to
have effect below a threshold voltage of
about 1.2V.
ABL functions as PIC/BRT-ABL (average
value type).
29 ABLFIL

the ABL control signal.
30 VTIM
V timing pulse output.
1k
Outputs the timing pulse from V sync
identification to the end of V blanking.
Pulses are positive polarity from 1 to 6V.

which has been expanded before and
after the V sync is superimposed and
output as the 1 to 3V pulse.
31 VD–OUT/VPROT

400µA 24k
V sawtooth wave output and V protect
signal input.
When a large current (3mA) is drawn
from this pin, the RGB outputs are all
blanked and "1" is output to the status
register VNG.
32 VD+OUT/VPROT

400µA
Serves as both a V sawtooth wave output
with the reverse polarity of VD–OUT,
and a Vprotect signal input. The Vprotect
function can even be applied to this pin.
