CXA3272R

Driver/Timing Generator for Color LCD Panels

Description

The CXA3272R 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 an 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.

Features

• Color LCD panels LCX032 and LCX033 driver

• Supports NTSC and PAL systems

• Supports 16:9 wide display

(letter box and pulse elimination display)

• Supports Y/color difference inputs and RGB inputs

• Supports OSD input

• Serial interface circuit

• Electronic attenuators (D/A converter)

• VCO (can be switched with an external oscillator

circuit)

• LPF

• Common voltage output circuit

• Sharpness function (during Y/color difference

input)

• 2-point γ correction circuit

• R, G, B signal delay time adjustment circuit

• Output polarity inversion circuit

• Supports AC drive for LCD panel during no signal
