描述
The TW9992 is a low power NTSC/PAL analog video decoder that is designed for automotive applications. It supports single-ended, differential and pseudo differential composite video inputs. Integrated short-to-battery and short-to-ground detection, advanced image enhancement capabilities such as the programmable Automatic Contrast Adjustment (ACA) and the MIPI-CSI2 output interface make the TW9992 an ideal solution for demanding automotive camera applications.
