MStar MST702 Small Size LCD TV Processor with video Decoder Preliminary Data sheet version 0.1 semicondctor GENERAL DESCRIPTION The Mst702 is a high quality ASIC for NTSC/PAL/SECAM car TV application It receives analog NTSC/PAL/SECAM CVBS and S-Video inputs from TV tuners dVD or VCR sources including weak and distorted signals, as well as analog video input from GPs systems. Automatic gain control (agc)and 10-bit 3-channel A/D converters provide high resolution video quantization With automatic video source and mode detection users can easily switch and adjust variety of signal sources. Multiple internal adaptive Plls precisely extract pixel clock from video source and perform sharp color demodulation Built-in line-buffer supports adaptive 2-D comb-filter, 2-D sharpening, and synchronization stabler in a condense manner. The output format of MST702 supports 3.5"w7 analog tFT-LCD modules. 3 10/28/2010 Copyright 2010 MStar Semiconductor, Inc.
