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.
