1. General Description
The HX8819AFAG/ HX8819AFBG/ HX8819AFCG are TFT-LCD timing controller with built-in dithering function. They provide horizontal and vertical control timing to TFT-LCD source and gate drivers. This controller performs polarity inverted function to convert 8-bit digital RGB data into 6-bit digital RGB data for TFT-LCD panel.
2. Features
Supporting display resolution WVGA 800RGB x 480(HX8819AFAG/ HX8819AFBG) and VGA 640RGB x 480 (HX8819AFCG) modes depend on different bonding option. Master clock frequency: 40 MHz max. Supporting 24-bits (8-bits x3) digital parallel RGB input signals Supporting both Sync(Hs/Vs) mode and Data enable (DE) mode Built-in dithering function. Built-in polarity inverted function. Provide the control timing of the source drivers and the gate drivers. Support dual clock function (HX8819AFBG and HX8819AFCG) Single supply voltage: +3.3V 64 TQFP
