TW8832S数据手册集成电路（IC）的视频处理规格书PDF

描述 Description

The TW8832 incorporates many of the features required to create multi-purpose in-car LCD display system in a single package. It integrates a high quality 2D comb NTSC/PAL/SECAM video decoder, triple High-Speed RGB ADCs, high quality scaler, and images enhancement functions which include Black and White Stretch and etc. It also supports panoramic scaling for conversion to wide screen display. On the input side, it supports a rich combination of CVBS, S-video, analog RGB as well as digital inputs. On the output side, it supports variety of digital panel types with its built-in timing controller.
