Overview
Description
The RAA279971 is a high-definition analog video encoder that is designed for automotive applications. It accepts digital video input using a 2-lane MIPI-CSI2 or a DVP/Pseudo BT.656 parallel interface and supports multiple high-definition resolutions up to 720p/60 or 1080p/30. The RAA279971 uses a built-in 10-bit video DAC that encodes the incoming video stream into an analog composite format that is transmitted to an RAA279972 decoder as a single-ended or differential signal over up to 30 meters of either coax or STP cable.
