Product Summary

The VX1818 is a high quality video processor IC for middle size LCD panel application inherited from VXIS 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 of the VX1818 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 the VX1818 directly supports 960/1200/1440x234 color TFT-LCD modules.
