LCD Driver
For the availability of this product, please contact the sales office.
Description
The CXA3512R is a driver IC for the analog inputs
of SVGA or higher Sony polycrystalline silicon TFT
LCD panels. It has a line invert amplifier and analog
demultiplexers, as well as the timing generator and
output buffers required for these. The CXA3512R
can directly drive an LCD panel. The VCOM setting
circuit and precharge pulse waveform generator are
also on-chip.
64 pin LQFP (Plastic)
Features
High-speed signal processing supports XGA high refresh signal
Overall wide band response
Low output deviation by on-chip output offset cancel circuit
Invert amplifier with 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
Precharge pulse waveform generation circuit
