No Preview Available ! CXA2112R LCD Driver For the availability of this product, please contact the sales office. Description The CXA2112R is a driver IC developed for use in the 6-input/12-input Sony polysilicon TFT LCD panel (LCX016/017). It has a line invert amplifier and analog de-multiplexers, timing generator and output buffers required for these. CXA2112R can directly drive analog inputs of LCX016/017. It is used one IC with the LCX016, and two ICs with the LCX017. The VCOM setting circuit and pre-charge pulse waveform generator are also on-chip. 64 pin LQFP (Plastic) Features • High-speed signal processing supports XGA high refresh signal (dot clock to 100MHz) • Overall wide band response • Low output deviation by on-chip output offset cancel circuit • Small phase delay difference between inverted signal and non-inverted signal • On-chip timing generator with ECL • Dot clock phase adjustment function • VCOM voltage generation circuit • Pre-charge pulse waveform generation circuit Absolute Maximum Ratings • Supply voltage • Supply voltage • Operating temperature • Storage temperature • Allowable power dissipation VCC VDD PD 16 5.5 –20 to +70 –65 to +150 2300 V V °C °C mW (single layered board mounted) Operating Conditions • Supply voltage • Supply voltage VCC 15 to 15.5 VDD 4.75 to 5.25 V V Sony reserves the right to change products and specifications without prior notice.
