The SmartASIC SD2000A is a highly integrated TFT LCD

controller chip with the latest SmartASIC advanced image-

processing technology and an integrated ADC/PLL to form up

an ultra low cost solution supporting analog input. The

SD2000A has advanced programmable non-linear parametric

cubic based scaling engine with proprietary sharpness

adjustment and text enhancement. The SD2000A has robust

handling of a wide variety of TFT LCD panels and strong

support of standard or non-standard input timings.
