Description

The TDES9640 is a V 3Link Enhanced Vision deserializer that delivers robust ultra-high-speed 7.55 Gbps forward channel and 47.1875 Mbps bidirectional control channel for connecting up to 4 data sensors to the processing unit over a coaxial or STP cable. When paired with the TSER9615 or the TSER4905 serializers, the TDES9640 receives video data from image sensors or video sources supporting ultra-high resolutions or multiple sensors in various topologies.

Data is received and aggregated into two MIPI CSI-2 D-PHY or C-PHY outputs for interfacing with a downstream processor. An additional CSI port is used for port replication in D-PHY mode only. 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.

The TDES9640 supports advanced data protection and diagnostic features, as well as multiple levels of data integrity checking and protection in conjunction with programmable health status interrupt, which helps achieve robust sensor module and link operation in the end application.
