Setting of Input pins
Since 5 pins of SPIO, SPOI, CK, CTR, and MODE
of the input pins are not pulled up or pulled down in
the IC, never use these 5 pins in the "OPEN"
condition.
Since V
A
, V
B
, and V
C
pins are for inputting video
signals, necessary video signals must always be
input.
Except for V
A
, V
B
, V
C
, SPIO, SPOI, CK, CTR, and
MODE, all other input pins are pulled up in the IC.
However, to preventing malfunction due to noise
etc., avoid using the "OPEN" condition whenever
possible, and set to "H" level or "L" level.
Input video signals
Input video signals are target for analog signals
(continuous signals).
The input band of video signals is applicable up to
the maximum of 12.5 MHz.
Bypass capacitor
If the noise of a logic system is superposed on
analog circuits such as the sample and hold
circuits, analog characteristics (such as output
voltage deviation and dynamic range, etc.) may
deteriorate. For this reason, insert bypass
capacitors of about 1 μF between V
CC
L and GNDL,
V
CC
A and GNDA.
Fully evaluate and determine the value of bypass
capacitors with them actually mounted on the LCD
module.
Maximum ratings
When connecting or disconnecting the power
supply, this IC must be used within the range of the
absolute maximum ratings.
