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.
