The MST719DE is a high quality ASIC for NTSC/PAL/SECAM, and HDMI LCD-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 RGB and YCbCr. 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.  […]
