VX1818

Preliminary Product Brief DESCRIPTION VX1818 Video Processor for Middle Size LCD Panel VX1818 is a high quality video processor IC for middle size LCD panel application inherited from VXIS’s successful video decoder IP. The VX1818 transforms and decodes NTSC/PAL video signals from TV tuner, DVD, or VCR sources, including weak and distorted signals, into R/G/B video signals and directly drives the panel with build-in timing controller. The build-in automatic gain control (AGC) and 10-bit 2-channel AD converters maintain high-resolution video quality, and with automatic video source/mode detection, user can freely switch and adjust variety of signal source. The multiple internal adaptive PLLs also can help precisely extract pixel clock from video source and perform sharp-and-keen color demodulation. Adaptive 2-D comb-filter, 2-D sharpening, and synchronization equalizer are implemented with build-in line-buffers. The output format of VX1818 directly supports 960/1200/1440x234 color TFT-LCD modules.
