TW8804-LC3-GRSHV

Video Processing Overview

The TW8804 is an LCD flat panel controller integrating an NTSC/PAL/SECAM decoder and analog/digital RGB/FB input. It converts standard TV, DTV, and PC monitor signals to drive TFT panels up to 1280x1024 resolution with 1 or 2-pixel/clock formats. The chip features six ADCs, a 2/4H adaptive comb filter, and proprietary Y/C processing. It supports CVBS, S-video, YPbPr, and digital RGB/YCbCr inputs. Internal logic synchronizes frame rates, while an image-scaling engine handles resolution conversion. An internal de-interlacing engine supports interlaced video.
