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.
