TFT-LCD AV CONTROLLER
October, 2003, Version 0.2
PRELIMINARY
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.
