3 Description

The DS90UB9702-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 four 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. 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 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.
