Description

LCD panel AC drive inversion

timing input.

High: inverted

Low: non-inverted

See the Timing Chart.

Internal sample-and-hold timing

circuit reset pulse input.

This pin is also used as the

offset cancel level insertion

timing input.

A reset is applied to the internal

timing generator at the falling

edge.

Output phase adjustment.

The output phase is adjusted in

MCLK period units when

SL_DAT is high, and in

1/2 MCLK period units when

SL_DAT is low.

Signal center voltage (inversion

folded voltage) adjustment input.

The SH_OUT output center

voltage can be adjusted in the

range from 7.0 to 8.0V.

Output signal offset adjustment

from signal center voltage.

The SH_OUT output 100%

white level (at 3FF input) voltage

can be adjusted in the range

from 0 to 1V from the center

voltage.

Level output for canceling the

offset between channels.

Connect the CAL_L and

CAL_H, between ICs when

using two CXA7000R.
