Driver/Timing Generator for Color LCD Panels

Description

The CXA3572R is an IC designed to drive the color

LCD panel ACX306/312.

This IC greatly reduces the number of peripheral

circuits and parts by incorporating a RGB driver and

timing generator for video signals and a VCO 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 panel ACX306/312 driver

• Supports NTSC and PAL systems

• Supports Y/color difference and RGB inputs

• Supports OSD input

• Power saving function (clock stopped)

• Various setting control using a serial interface

circuit (asynchronous type)

• Electronic attenuators (D/A converter)

• VCO (no external oscillator circuit)

• LPF (fc variable)

• COMMON and PSIG output circuits

• Sharpness function

• 2-point

γ correction circuit

• R, G, B signal delay time adjustment circuit

• Sync separation circuit

• D/A output pin (0 to 3V, 8 level output)

• Output polarity inversion circuit

• Supports AC drive for LCD panel during no signal

Applications

Compact LCD monitors, etc.
