Texas Instruments DS90UB9702-Q1 FPD-Link Deserializer
Texas Instruments DS90UB9702-Q1 FPD-Link Deserializer delivers robust ultra-high-speed 7.55Gbps forward channel and 47.1875Mbps bidirectional control channel. These channels connect up to four raw data sensors to central processing units over an automotive coaxial or STP cable. When coupled with the Texas Instruments 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. An additional CSI port is used for port replication. 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 and 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 a programmable health status interrupt, help ensure robust sensor module and link operation in vehicles.
