CXA3017R
Decoder/Driver/Timing Generator for Color LCD Panels
For the availability of this product, please contact the sales office.
Description
The CXA3017R is an IC designed to drive the color
LCD panels LCX005BK/BKB, LCX009AK/AKB,
LCX024AK/AKB, LCX027AK/AKB and DCX501BK.
This IC allows two-panel simultaneous and switching
drive by simultaneously outputting the timing pulses
for the LCX005BK/BKB, LCX009AK/AKB, LCX024AK/AKB,
LCX027AK/AKB and DCX501BK.
This IC greatly reduces the number of peripheral
circuits and parts by incorporating an RGB decoder,
driver, and timing generator for video signals onto a
single chip. This chip has a built-in serial interface
circuit and electronic attenuators which allow various
settings to be performed by microcomputer control,
etc.

Description
External digital signal inputs.
There are two thresholds: Vth1
(= 1.0V) and Vth2 (= 2.0V).
When one of the RGB signals
exceeds Vth1, all of the RGB
outputs go to black level; when
an input exceeds Vth2, only
the corresponding output goes
to white level.
Connect these pins to GND
when not used.
External trap connection.
Connect the trap between this
pin and GND to eliminate the
chroma component.
Leave this pin open when
using Y/C and Y/color
difference mode.
DAC output.
8-level, 7-step DC voltage from
approximately 0.2 to 2.9V is
output from this pin.
DCX501BK up/down and
right/left inversion switching.
These pins are open collector
outputs, so first connect a
100kΩ resistor between these
pins and the panel VDD (15.5V)
and then connect to the
DCX501BK.
