T0308S

T0308S

1. General Description

T0308S is a highly integrated video control SoC with Digital LCD/TFT panel displaying controller and could support parallel RGB panel, sRGB panel, ITU656 panel, digital TCON and CPU panel.  AMT630A integrates a video decoder and a digital TFT-LCD Panel Control. It accepts analog NTSC / PAL / SECAM CVBS signals from TV tuner, DVD, or VCR sources, including weak and distorted signals. Automatic gain control (AGC) and 9-bit 1-channel A/D converters provide high resolution video quantization, with automatic video source and mode detection. User can easily switch and adjust variety of signal source. Multiple internal adaptive PLL could precisely extract pixel clock from video source and perform sharp-and-keen color demodulation. Build-in line buffer supports adaptive 2-D comb-filter, 2-D sharpening, and synchronization stable in a condense manner. Build-in On Screen Display (OSD) module is very flexible and easy programming. AMT630A is perfect excellent efficiency for a low-cost Price and small-area PCB solution.
