TW8836数据手册集成电路（IC）的视频处理规格书PDF

描述 Description

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, a high-quality scaler and deinterlacer, and a versatile OSD, with a high-performance output panel interface for MCU and LVDS or TTL.

The TW8836 can support input resolutions up to 1080p and can drive LCD panels at resolutions up to 1366 x768. The TW8836's video processing capability includes arbitrary H/V scaling, panoramic scaling, image mirroring, image adjustment and enhancement, and black and white stretch. The feature set and versatility of this device makes it an ideal solution for in-car LCD display applications and portable display applications such as pico projectors.
