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.
