Automatic gain control (AGC)and 10-bit3-Channel A/D converters provide high resolution video quantization. With automatic video source and modedetection, users can easily switch and adjust variety of signal sources. Multiple internal adaptive PLls preciselyextract pixel clock from video source and perform sharp color demodulation Built-in line-buffer supportsadaptive 2-D comb-filter, 2-D sharpening and synchronization stabler in a condense manner. the outputformat of MST705 supports 6-bit TTL/TCON and Lvds digital TFT-LCD modules.Mstar confidentialforInternal Use only311/22010Copyright 2010 MStar Semiconductor, Inc.
