DATA SHORT To request the full datasheet, please visit www.intersil.com/products/TW8836 TW8836 FN8645 Rev 5.00 November 3, 2016 LCD Video Processor with Built-In Decoder, TTL/LVDS Inputs, MCU, OSD, and TTL/LVDS Panel Interface Features The TW8836 is a highly integrated LCD video processor that incorporates many of the features required to create a multipurpose LCD display system into a single package. This includes a high quality, 2D comb NTSC/PAL/SECAM video decoder, triple high-speed RGB ADCs, an LVDS and TTL digital input interface, high-quality scaler and deinterlacer, as well as a versatile OSD, high-performance MCU and LVDS or TTL output panel interface. The TW8836 can support input resolutions up to 1080p and can drive LCD panels at resolutions up to 1366x768. The TW8836's video processing capability includes arbitrary H/V scaling, panoramic scaling, image mirroring, image adjustment and enhancement, black and white stretch, etc. The feature set and versatility of this device makes it an ideal solution for in-car LCD display applications, as well as portable display applications such as pico projectors.
