Operating Modes—Six-Channel Systems
The simplest full color LCD-based system is characterized by an
image processor with a single 10-bit-wide data bus and a 6-channel
LCD per color.
Such systems usually have VGA or SVGA resolution and require a
single AD8381 per color.
The INV input facilitates column and row inversion for
these systems.

Operating Modes—12-Channel Systems
Single and dual data bus type 12-channel systems are com-
monly in use.
The single data bus 12-channel system is characterized by an
image processor with a single, 10-bit data bus and a 12-channel
LCD per color. The maximum resolution of such a system is
usually up to 85 Hz XGA or 75 Hz SXGA and requires two
AD8381s per color.
One AD8381 is set to run in EVEN mode while the other is in
ODD mode. Both AD8381s share the same data bus and CLK.
The timing diagram of such a system is shown in Figure 8.
The dual data bus 12-channel system is characterized by an
image processor with two 10-bit parallel data buses and a
12-channel LCD. The maximum resolution of such a system
is usually up to 75 Hz UXGA and requires two AD8381s per color.
Both AD8381s may be set to run in EVEN mode and may share
the same CLK. The timing diagram of each AD8381 in such
a system is identical to that of the 6-channel system.
The INV input facilitates column, row, and pixel inversion for
both types of 12-channel systems.

To facilitate 18, 24, or higher channel systems, any number of
required AD8381s may be cascaded.
