This includes a high quality 2D comb NTSC/PAL/SECAM video decoder which supports both Digital Inputs Support single-ended and differential CVBS signals, an LVDS and Supports both BT.656 and 601 video formats with TTL digital input interface, high quality scaler and H/VSYNC deinterlacer, a font OSD engine, and LVDS, TTL or TCON output panel interfaces. The TW8834 can support input Supports RGB 24-bit input up to 1080p resolution resolutions up to 1080p and can drive LCD panels at Single channel LVDS (open LDI) input up to 720p resolutions up to 1366 x 768. The TW8834s video resolution processing capability includes arbitrary H/V scaling, panoramic scaling, image mirroring, image adjustment TFT Panel Support and enhancement, black and white stretch, etc. This device can support fast boot system requirements and Built-in programmable timing controller provides stability and reliability to the system due to the Supports 3, 4, 6 or 8 bits per pixel up to 16.8 million fact that it is a hardwired solution that can sync to the colors with built-in dithering engine video source and display an image on the LCD in less Supports digital panels (TTL) or single channel LVDS then 0.5 seconds from start up. The feature set and panels up to WXGA (1366 x 768) resolution, 85MHz versatility of this device makes it an ideal solution for in-car LCD display applications.
