CXA3522R
Driver/Timing Generator for Color LCD Panels
Description
The CXA3522R is an IC designed to drive the color
LCD panel ACX306.
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.
Features
• Color LCD panel ACX306 driver
• Supports NTSC and PAL systems
• 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)
• COMMON and PSIG output circuits
• Sharpness function
• 2-point
γ correction circuit
• R, G, B signal delay time adjustment 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.
