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. The device also provides 8 different zoom in/zoom out display modes for 2 different display resolutions.
