description
The TW8820 employs many of the features needed to create a multipurpose video door telephone intercom LCD display in a single package system. It integrates a high-quality 2D comb NTSC/PAL/SECAM video decoder, high-quality scaling, image enhancement features including elastic and gamma correction in black and white. It also supports panoramic scaling converted to widescreen monitors. TW8820 supports analog composite video input and output, supports a variety of digital LCD panels, and its built-in timing controller type.ISL9110A
