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
