CXA3017R
Decoder/Driver/Timing Generator for Color LCD Panels For the availability of this product, please contact the sales office.
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 64 pin LQFP (Plastic)
