HX8806 Data Sheet TFT-LCD AV CONTROLLER Preliminary Version 0.2 October, 2003 Himax Technologies, Inc. 1F, No.12, Nanke 8th Road, Tainan Science-Based Industrial Park, Tainan County, Taiwan 741, R.O.C. TEL: 886-6-505-0880 FAX: 886-6-505-0891 DOC No:HX8806-17 HX8806 TFT-LCD AV CONTROLLER PRELIMINARY October, 2003, Version 0.2 1. General Description The HX8806 is a timing controller for small panel TFT-LCD. It provides horizontal and vertical control timing to TFT-LCD source and gate drivers. Built-in vertical synchronization detection circuit generates vertical synchronization signal internally without the extra components. Built-in phase lock loop sub-function with external VCO and low pass filter produces system clock which synchronizes input composite synchronization signal. HX8806 also provides 8 different zoom in/zoom out display modes for 2 different display resolutions. 2. Features Programmable resolution mode. Master clock frequency: 30 MHz max. Built-in vertical sync. detection to omit the external sync. separator. Supply voltage: +5.0V or +3.3V. Shift clock signals for the source driver (3-φ Clock). Line inversion driving scheme. Support NTSC/PAL TV system. Provides control timings for source and gate drivers. Provides flip and mirror scan control. Built-in zoom in/zoom out display mode selection. 48 pins LQFP.
