DS90UB9722-Q1中文资料适用于 8MP+ 摄像头、雷达和其他传感器、具有 D-PHY CSI-2 输出端口的 FPD-Link IV 双路解串器集线器数据手册TI规格书

描述 Description

The DS90UB9722-Q1 is an FPD-Link deserializer that delivers robust ultra-high-speed 7.55 Gbps forward channel and 47.1875 Mbps Bidirectional Control Channel for connecting up to two raw data sensors to central processing units over an automotive coaxial or STP cable. When coupled with DS90UB971-Q1 serializer, the deserializer receives video data from imagers supporting ultra-high resolutions (8MP+/40fps) or multiple sensors in various topologies.

Data is received and aggregated into two MIPI CSI-2 D-PHY outputs for interfacing with a downstream processor. The flexible MIPI CSI-2 outputs support multiple virtual channels interleaving per port to differentiate multiple sensors, exposures, and data types. This functionality features video aggregation and replication modes and supports input-to-output port as well as virtual channel (VC-ID) remapping.

Advanced data protection and diagnostic features support overall system functional safety. Multiple levels of data integrity checking and protection in conjunction with programmable health status interrupt helps ensure robust sensor module and link operation in vehicles.
