CXA2000Q

Connect a capacitor to form the LPF of

the ABL control signal.

ABLIN/VCOMP

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).

ABLFIL

VTIM

V timing pulse output.

Outputs the timing pulse from V sync

identification to the end of V blanking.

Pulses are positive polarity from 1 to 6V.

During zoom mode, the V blanking pulse

which has been expanded before and

after the V sync is superimposed and

output as the 1 to 3V pulse.

VD–OUT/VPROT

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

VD+OUT/VPROT

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.
