3 Description
The TDES9640 is a V3Link 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.
