CXA2111R

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 –0.3 to +5.5 V Supply voltage VCC Input voltage VI –0.3 to VCC + 0.3 V Storage temperature Tstg –65 to +150 °C Allowable power dissipation PD 1000 mW Operating Conditions Supply voltage Digital input voltage high Digital input voltage low Operating temperature VCC VH VL Topr 4.75 to 5.25 2.2 to VCC 0 to 0.8 –20 to +70 V V V V Sony reserves the right to change products and specifications without prior not...
