First dual-port CSI-2 quad deserializer
hub enables faster, more flexible ADAS
applications
TI deserializer hub aggregates and replicates data from
multiple high-resolution sensors in automotive camera
and radar applications
Texas Instruments (TI) (NASDAQ: TXN) today
introduced the industry’s first dual-port quad deserializer
hub that is compliant with the MIPI Camera Serial
Interface 2 (CSI-2) specification. The new automotive-
qualified hub simultaneously aggregates and replicates
high-resolution data from up to four cameras. High data
throughput and precision are essential in autonomous
driving and sensor fusion-based advanced driver
assistance systems (ADAS), including surround-view
systems, rearview cameras, driver-monitor cameras,
camera-monitor systems, front camera systems and
satellite radar equipment. For more information, see

more video data at faster speeds in equipment designed
to recognize pedestrians, bicyclists and other obstacles
in a vehicle’s path or periphery. The DS90UB964-Q1
FPD-Link III device’s dual CSI-2 outputs with virtual
channel ID mapping and port replication save processor
resources to speed processing of data from up to four
cameras at 100 MHz per sensor and 12-bit resolution.
In addition, TI’s adaptive equalization (EQ) provides
diagnostics that enable the system to monitor cable
health and take action before cable failure occurs.
Key features and benefits of the new DS90UB964-Q1
quad deserializer hub
Faster video processing: Dual-port CSI-2 outputs
support video transmission at up to 1.6 Gbps per lane
for higher bandwidth and faster obstacle recognition by
supporting the following:
 The second CSI-2 port enables simultaneous
video replication for data logging, or separate viewing
and machine-vision flows.
 The new hub, unlike competitive devices,
supports virtual channel ID mapping which helps
processors differentiate cameras and high-dynamic-
range exposures, enabling more efficient processing.
 The ultra-low-latency control channel enables
integration of the image signal processing (ISP) function
into the electronic control unit (ECU), and out of the
camera, improving image quality and reducing system
costs.
Robust system operation and diagnostics: Like other
devices in TI’s growing FPD-Link III serializers-
deserializer (SerDes) family, the DS90UB964-Q1
features adaptive receiver EQ rather than transmitter
pre-emphasis. Adaptive EQ automatically compensates
for cable aging and bending effects to ensure optimal
signal quality, and helps reduce electromagnetic
interference (EMI).
Cost-optimized, flexible system design: TI’s broad
portfolio of interoperable, upward- and downward-
compatible FPD-Link III SerDes devices support
automotive manufacturers and tier-1 suppliers’ high-
, mid- and entry-level performance configurations.
This scalability makes it easy for designers to select
and design in the best SerDes to optimize system
performance and cost.
The DS90UB964-Q1 deserializer hub can work with
many processors on the market today, including the
TDA3x SoC processor for ADAS. The power-over-
coax support in both devices enables engineers to
significantly reduce the wiring needed in their systems.
In addition to the DS90UB964-Q1 1-megapixel (MP)
deserializer hub, TI is now sampling SerDes devices for
2-MP cameras at 60 frames per second. These 2-MP
devices feature synchronous clocking, and advanced
data protection and diagnostic features.
Tools and support to speed design
Engineers can quickly and easily evaluate the new
deserializer hub with the DS90UB964-Q1 evaluation
module (DS90UB964-Q1EVM), available today for
US$499 from the TI store and authorized distributors.
Designers can also jump-start their system design
using the new device with a TI Designs reference
design. Check out the Automotive ADAS 4 Camera Hub

Coax.
