Overview
CXA2111R LCD Signal Processor (Gamma Correction) Description The CXA2111R is a signal processor IC developed for LCD panels.
Gamma correction, gain and bias, etc.
, can be adjusted using the I2C bus and external adjustment pins.
The output of this IC is ideal as the input of the CXA2112R (LCD sample-and-hold driver IC), and the sample-and-hold position, etc.
, can also be adjusted using the I2C bus.
Features • Independent R, G and B gamma adjustment • Three-point gamma gain and position adjustment (one white side point, two black side points) • Independent R, G and B output amplifier gain and bias adjustment • Various I2C bus-based controls and adjustment of various characteristics by external DC input • Input signal clamp function (variable clamp voltage) • Black side limiter adjustment • CXA2112R adjustment output • Precharge output (for CXA2112R) • High frequency response • High slew rate output Applications • Liquid crystal projectors • Compact liquid crystal monitors Structure Bipolar silicon monolithic IC 52 pin LQFP (Plastic) Absolute Maximum Ratings –0.
