CXA3503R
Driver/Timing Generator for Color LCD Panels
Description
The CXA3503R is an IC designed to drive the color
LCD panels LCX032 and LCX033.
This IC greatly reduces the number of peripheral
circuits and parts by incorporating a RGB 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.
72 pin LQFP (Plastic)
Features
Color LCD panel LCX032 and LCX033 driver
Supports NTSC and PAL systems
Supports 16:9 wide display (letter box and pulse
elimination display)
Supports Y/color difference and RGB inputs
Supports OSD input (digital input)
Power saving function
Serial interface circuit
Electronic attenuators (D/A converter)
Trap and LPF (f0, fc variable)
