Description The CXA3017R is an IC designed to drive the color LCD panels LCX005BK/BKB, LCX009AK/AKB, LCX024AK/AKB, LCX027AK/AKB and DCX501BK. This IC allows two-panel simultaneous and switching drive by simultaneously outputting the timing pulses for the LCX005BK/BKB, LCX009AK/AKB, LCX024AK/AKB, LCX027AK/AKB and DCX501BK. This IC greatly reduces the number of peripheral circuits and parts by incorporating an RGB decoder, driver, and timing generator for video signals onto a single chip. This chip has a built-in serial interface circuit and electronic attenuators which allow various settings to be performed by microcomputer control, etc. Features • Color LCD panel LCX005BK/BKB, LCX009AK/AKB, LCX024AK/AKB, LCX027AK/AKB and DCX501BK driver • Supports two-panel simultaneous and switching drive using the LCX005BK/BKB, LCX009AK/AKB, LCX024AK/AKB, LCX027AK/AKB and the DCX501BK • Supports NTSC and PAL systems • Supports 16:9 wide display (letter box and pulse elimination display) • Supports composite inputs, Y/C inputs and Y/color difference inputs • Serial interface circuit • Electronic attenuators (D/A converter) • VCO • BPF, trap and delay line • Sharpness function • 2-point γ correction circuit • R, G, B signal delay time adjustment circuit • Polarity inversion circuit (line inverted mode) • Supports external RGB input • D/A output pin (0 to 3V, 8 levels) • Supports AC drive for LCD panel during no signal Applications • Compact LCD monitors • LCD viewfinders • Compact liquid crystal projectors, etc.
