CXA3572R
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.
