1. General Description
AMT630 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. AMT630 integrates a video
decoder and an Analog TFT‐LCD Panel Control. It accepts analog NTSC / PAL / SECAM CVBS signals and S‐Video from
TV tuner, DVD, or VCR sources, including weak and distorted signals. Automatic gain control (AGC) and 9‐bit 2‐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 flexiable and easy programming. DC/DC, DC/AC, VCOM, etc. modules are cost effective for low cost
and small area PCB solutions.
