描述

The RAA279974 is a 4-channel high-definition analog video decoder designed for automotive applications. It supports single-ended, differential, and pseudo-differential analog composite high-definition Automotive High-Definition Link (AHL) video inputs. Four high-quality 10-bit video ADCs convert the analog signals to digital, and a proprietary AHL adaptive comb filter separates the Luma and Chroma data to output a YUV422 digital video signal over a MIPI-CSI2 interface. In addition, the RAA279974 has integrated short-to-battery and short-to-ground detection and image enhancement capabilities, making it an ideal solution for demanding high-resolution automotive camera applications. This device works in conjunction with the RAA279971 AHL analog video encoder, which sits in the camera module.
